Generation of third-harmonic spin oscillation from strong spin precession induced by terahertz magnetic near fields

Generation of third-harmonic spin oscillation from strong spin precession induced by terahertz magnetic near fields

The authors studied HoFeO3 crystal using multicycle THz magnetic pulses enhanced strongly by spiral-shaped microstructure. The observed Faraday ellipticity demonstrates second- and third-order harmonics of the magnetization oscillation and an asymmetric oscillation behavior.
