Effective rectification of THz electromagnetic fields in a ferrimagnetic iron garnet

T. G. H. Blank, E. A. Mashkovich, K. A. Grishunin +5

It is found that single-cycle THz electromagnetic fields efficiently excite a GHz spin resonance mode in ferrimagnetic Tm${}_3$Fe${}_5$O${}_{12}$, despite the near absence of GHz spectra…
