POLAR AND LONGITUDINAL MAGNETOOPTIC KERR-EFFECT IN PT NI AND PD/NI MULTILAYERS/

The paper deals with the magnetooptical spectroscopic studies of Pt/Ni and Pd/Ni multilayers. The films were grown onto glass (Pt/Ni) and mi ca (Pd/Ni) substrates by dual electron beam evaporation. In the Pt/Ni set the thickness of Pt layers was kept constant at 2 nm while that of Ni layers was 1.2 and 2.9 nm. For the Pd/Ni set the individual Ni and Pd layer thicknesses varied between 1 and 10 monoatomic layers. Simul taneous polar and longitudinal magnetooptical Kerr rotation and ellipt icity experiments were carried out in the spectral range between 1.5 a nd 5.2 eV. The observed Line broadening, shift and/or splitting are as signed to an effect of the interface Ni-Pd (or Ni-Pt) layers.
