X-ray diffraction pattern and field emission scanning electron microscope images approve the formation of LaFeO 3 and HoMnO 3 phases without the presence of any extra phase. These composites reveal the strain mediated magnetoelectric effect with longitudinal (α E33) and transverse (α E31) configurations at lower frequency region under an external magnetic field. Maximum values of α E31 and α E33 are found to ~ 0.54 and ~ 0.31 mV/cm-Oe, respectively for 0.3LaFeO 3-0.7HoMnO 3 nanocomposites. The electronic transport has been examined by impedance spectroscopy technique for understanding the grain boundary and grain effects in resistive and capacitive behavior of the materials considering an idealized simulated circuit. Temperature dependent Nyquist plots show the non-Debye type phenomena as well as semiconductor in nature (i.e., negative temperature coefficient of resistance) of the materials. Electrical susceptibility reveals the domain motion of the system, which is corresponding to the electrostriction property. The electrical conductivity with frequency follows the Joncher's single power law and it is controlled through large and small polaron tunneling model. The synthesized nanocomposites are a capable candidate to offer some helpful ideas for developing the lead free device applications.

The improvement of dielectric properties in polymer-based hybrid LaFeO3–PVDF nanocomposites can be utilized to make a suitable memory storage device. Surface modified LaFeO3 (LFO) nanoparticles are well distributed inside the polymer resulting in improved dielectric constant and reduced dielectric loss. The study of complex and modulus impedance spectroscopy (IS) shows some interesting results for an influence of grain and grain boundary effects of electrical conductivity attributing the non-Debye type phenomena. The change of relaxation frequency with an applied magnetic field is ascribing the spin-dependent mechanism of electrical transport at grain boundaries (GBs).

The observed room temperature magnetoelectric coefficient is enhanced with the increase of LaFeO 3 content in nanocomposites. The maximum value of magnetoelectric coupling is found to be 1.5mV/cm−Oeand1.5 mV/cm-Oe and 1.5mV/cm−Oeand0.3 mV/cm-Oe, which may be due to the strain mediation of piezomagnetic phase and magnetodielectric property of the material. The frequency dependent AC conductivity at several temperatures indicates the thermally activated conduction process in the system. The electrical conductivity (both AC and DC) shows positive temperature coefficient resistance effect of the system where AC conductivity obeys Jonscher's power law. It demonstrates the hopping mechanism via small as well as large polaronic conduction process in the system. Maximum change of magnetoimpedance ($185%) is observed at a frequency of 100 Hz at room temperature. The observed magnetoimpedance effect can be explained considering the skin effect. The magnetocapacitance effect shows the maximum value ($60%) at lower frequency regime at room temperature attributing the evidence of Maxwell-Wagner interfacial or space charge polarization in the sample. At room temperature the magnetic field dependent capacitance of these samples is corroborating the evidence of magnetoelectric coupling.

The X-ray diffraction pattern indicates that both LaFeO 3 and poly(vinylidene fluoride) phases coexist in the nanocomposites. The magnetoelectric coupling measurement confirms the multiferroic in nature of the nanocomposites. Magnetoelectric and magnetocapacitance (~ 42%) effects are ascribing the improvement of space charge polarization of nanocomposites. The light of classical electrodynamics causes the room temperature magnetoimpedance effect (~ 94%). Temperature dependent ac conductivity suggests the observation of negative temperature coefficient resistance behavior that also obeys the single Jonscher's power law. The conduction mechanism of the system is controlled through small and large polaronic hopping. Activation energy of those polymer based hybrid nanocomposites is estimated using Arrhenius relation. The magnetoelectric coupling of the nanocomposites is enhanced with an increase in poly(vinylidene fluoride) content. The inorganic-organic based nanocomposites could be a favorable candidate for improvement of magnetoelectric devices, smart energy storage and energy harvesting device applications.

In this direction, our study unveiled the capability of a biphase of bismuth pyrochlore and spinel in hosting a multiferroic order at room temperature. A complex oxide biphase of cubic pyrochlore and cubic spinel crystals acquired in the Bi 2 O 3-Nb 2 O 5-2MnCO 3-Fe 2 O 3 system revealed the crystals of a spinel phase (Fe 1.59(3) Mn 1.39(3) O 4.26(7)) intergrown in the dense pyrochlore (Bi 1.35(1) Fe 0.64(1) Nb 1.26(1) Mn 0.75(1) O 6.39(5)) matrix. The average composition of the components of the investigated biphase was determined using an electron probe microanalyzer (EPMA). The structural features indicated the presence of large ionic displacements within the cubic pyrochlore phase as seen from the appearance of 442 reflection in the X-ray diffraction pattern and infrared active mode at ∼64 cm −1 in the Raman spectrum recorded at room temperature. The pyrochlore singlephase composition (Bi 1.35(1) Fe 0.64(1) Nb 1.26(1) Mn 0.75(1) O 6.39(5)), as suggested from a thorough EPMA microstructural analysis, exhibited broad dielectric relaxation and an overall paramagnetic behavior. The observation of disordered superparamagnetism as well as dielectric relaxation in the biphase conformed to that of a relaxorlike multiferroic behavior at room temperature. Moreover, self-biased magnetoelectric voltage coefficients of 0.60 mV/cm Oe at 100 Hz and 5.54 mV/cm Oe at 1 kHz were detected between magnetization and electric polarization at room temperature. Therefore, the composite of such a pyrochlore and spinel with an inherent property of strong spin-orbit and spin-lattice coupling will be interesting from theoretical and experimental point of view in the arena of magnetoelectrics.

Dielectric constant of these nanoparticles gives the evidence of space charge polarization in the sample at lower frequency regime. Maximum magnetodielectric effect is obtained to ~ 61% at room temperature for particle size of ~ 21 nm, which may be due to the large surface to volume ratio of this nanoparticles compared to other particles size attributing the enhancement of space charge polarization. The maximum value of magnetoimpedance is found to ~ 92% for ~ 21 nm nanoparticle at room temperature. Magnetic field and frequency dependence room temperature magnetoimpedance are decreased with particles size of the nanoparticles. This behaviour has been explained through the light of classical electrodynamics, which reveals that this effect is depending on the magnetic field and ac signal frequency. Impedance spectroscopy is employed to study the electrical transport properties of the samples considering an equivalent circuit model for the effect of nanometric grain size. The electrical relaxation process of these materials is temperature dependent. Furthermore, ac conductivity curves follow the Jonscher's power law for electrical conduction process of the system through polaronic hopping.

Coexistence of both phases in nanocomposites is confirmed by X-ray diffraction technique. Electrical susceptibility corresponds to the domain wall motion due to electrostriction property. Temperature-dependent impedance analysis provides the evidence of space charge accumulation in nanocomposites exhibiting negative temperature coefficient resistance effect of the sample. The estimated activation energy from the Arrhenius fit suggests the hopping of carriers between La 2+ and La 3+ and Fe 2+ and Fe 3+ ions in the materials. The importance of the present study is the developing urge to know the details of magnetoelectric coupling and transport properties of a system for its technological applications.
