Research paper thumbnail of Magnonlike Dispersion of Spin Resonance in Ni-doped BaFe_{2}As_{2}

Physical Review Letters, 2013

Whereas the resonance is sharply peaked at Q AFM along the orthorhombic a axis, the resonance disperses upwards away from Q AFM along the b axis. In contrast to the downward dispersing resonance and hour-glass shape of the spin excitations in superconducting cuprates, the resonance in electron-doped BaFe2As2 compounds possesses a magnon-like upwards dispersion.
