Coherent Spin Waves in Thin-Film GaMnAs

Not Accessible

Your library or personal account may give you access

Abstract

Using pump-probe techniques we study coherent magnons in the ferromagnetic semiconductor GaMnAs. The magnetic anisotropy and spin stiffness constants are determined from the magnetic-field dependence of the frequency of the standing spin waves.
