We have reported the enhanced longitudinal Kerr effects of permalloy (Py) film deposited on an Ag/Bi bilayer in the near-infrared region. Moreover, enhancement of polar Kerr effects of the same sample was observed in the visible light region. Therefore, we investigate here the magnetization dynamics in the Py/Ag/Bi trilayers by using time-resolved magneto-optical Kerr effects.
