Abstract
The second optical harmonic generation and magnetooptical Kerr effect are i nvestigated for the light (lambda = 800 nm) reflected by ferromagnet-semico nductor heterostructures CaF2/MnAs/Si(111). The observed change in the seco nd-harmonic intensity is odd in magnetization. A phenomenological analysis of possible contributions to the second harmonic is carried out, and the so urces of optically nonlinear signals are determined from the experimental a zimuthal dependences of the light intensity at double frequency. The differ ence in the field dependences of the second harmonic and the magnetooptical Kerr effect is observed. (C) 2000 MAIK "Nauka/Interperiodica".
