Abstract
The Photoinduced magnetization in ferromagnetic (Ga, Mn)As thin films was reported. It was found that the optically generated spin-polarized holes changes the orientation of ferromagnetically coupled Mn spins and caused a large changed in magnetization, being 15% of the saturation magnetization, without the application of magnetic field. The results suggested that a small amount of non equilibrium carrier spins can cause collective rotation of Mn spins, presumably through the p-d exchange interaction.
