Abstract
Ferromagnetic-semiconductor heterostructures CaF2/MnAs/Si(111) have been st udied by two complementary magneto-optical techniques: magnetization-induce d second harmonic generation and linear magneto-optical Kerr effect. Crysta llographic and magnetic contributions to SHG are separated on the base of t he rotational anisotropy method. Magnetic hysteresis loops measured by SHG and Kerr effect exhibit different behavior due to different sensitivity of the two optical techniques to the interface, surface and bulk properties.
