We have observed dielectric glass behavior around 90 K, at the magnetic transition, which indicates that this behavior is predominantly magnetic in its origin. The magnetic field dependent dielectric constant in the magnetically ordered state tracks the features in isothermal magnetization thereby establishingmagnetodielectric coupling in this compound.

Metallic PdCrO2 and insulating LiCrO2, consisting of layered triangular arrangement of Cr+3, exhibits antiferromagnetic nature with two dimensional (2D) frustration. Recent studies reveal the presence of the spin correlation in a wide temperature range well above magnetic ordering temperature TN. It is of interest to investigate whether the frustration can be released by the application of external pressure or magnetic field in metallic and insulating environment in this structure. We have carried out magnetization under external hydrostatic pressure (up to 10 kbar) and heat capacity under high magnetic field of 140 kOe on these systems. The result reveals robust nature of the frustrated antiferromagnetic system irrespective of whether compound is metallic or insulating.

It was observed that the magnetic ordering is broadened and transition temperature is marginally reduced in the fine particles. Our results reveal that, with the decrease in particle size, spin glass-like behavior is observed in this compound.

The combined studies of dc magnetization, heat capacity and dielectric measurements confirm the coupling between electric and magnetic order parameters. Extensive in-field dielectric measurements as a function of magnetic field provide evidence for linear magnetodielectric effect near TN.
