Observation of terahertz-induced dynamical spin canting in orthoferrite magnon by magnetorefractive probing
Spin dynamics induced by intense terahertz pulses are commonly observed by magnetooptical effects. Here, we show that magnetorefractive effect provides a second-harmonic magnon signal whose amplitude is comparably strong with the linear component, making it an efficient probe for detecting the inher...

| Summary: | Spin dynamics induced by intense terahertz pulses are commonly observed by magnetooptical effects. Here, we show that magnetorefractive effect provides a second-harmonic magnon signal whose amplitude is comparably strong with the linear component, making it an efficient probe for detecting the inherent nonlinear spin dynamics in orthoferrites. |
