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 spectral components in the exciting THz pulse. By analyzing how the efficienc

Giant widening of interface magnetic layer in almost compensated iron garnet

Autor: Kudasov, Y. B., Logunov, M. V., Kozabaranov, R. V., Makarov, I. V., Platonov, V. V., Surdin, O. M., Maslov, D. A., Korshunov, A. S., Strelkov, I. S., Stognij, A. I., Selemir, V. D., Nikitov, S. A.

A two-sublattice ferrimagnet undergoes a transition from a collinear to canted magnetic phase at magnetic field oriented along an easy magnetization direction. In this work, we study the transition by means of the magneto-optical Faraday effect in a

THz Field-induced Spin Dynamics in Ferrimagnetic Iron Garnets

Autor: Blank, T. G. H., Grishunin, K. A., Mashkovich, E. A., Logunov, M. V., Zvezdin, A. K., Kimel, A. V.

Publikováno v: Phys. Rev. Lett. 127, 037203 (2021)

THz magnetization dynamics is excited in ferrimagnetic thulium iron garnet with a picosecond, single-cycle magnetic field pulse and seen as a high-frequency modulation of the magneto-optical Faraday effect. Data analysis combined with numerical model
