Research Abstract

The purpose of this study is to estimate the spin polarization of conduction electrons inferromagnetic metals by using pump probe technique. Firstly, we have grown various ferromagnetic metal thin films with different spin polarization. Spin relaxation of electrons in a semiconductor quantum well, which was excited by irradiating with circularly polarized light, was then measured using pump-probe magneto-optical Kerr effect technique. We have also made an attempt at measuring the spin relaxation of ferromagnetic thin films.
