Autor: Mikhail Gaponov, Sergey Ovcharenko, Nikita Ilyin, Elena Mishina

Publikováno v: Condensed Matter, Vol 7, Iss 4, p 55 (2022)

We experimentally demonstrate that the excitation of a silicon-doped yttrium-iron garnet film by femtosecond laser pulses triggers a magnetization precession with an amplitude determined by the external magnetization direction. The maximum efficiency
