Single-pulse terahertz coherent control of spin resonance in a canted antiferromagnet


We report on the coherent control of terahertz (THz) spin waves in a canted antiferromagnet, YFeO<sub>3</sub>, associated with a quasi-ferromagnetic spin resonance at a frequency of 0.3 THz, using a single THz pulse. The intrinsic dielectric anisotropy of YFeO<sub>3</sub> in the THz range allows for coherent control of both amplitude and phase of the… (More)
