Abstract :
In this paper, YFe2(110) single crystal films with Laves phase structure were grown on sapphire substrates by molecular beam epitaxy, and its magenization reversal was investigated by magneto-optical Kerr effect measurements. Results show that the film´s magnetic behavior is governed by the combined effect of induced shape anisotropy and intrinsic four-fold magneto-crystalline anisotropy. A dominant uniaxial in-plane anisotropy can be created by geometrical effects.
