Abstract: | The effect of nanosecond laser pulses on the optical and magnetic properties of Bi-SiC-TbFe-SiC, SiC-TbFe-SiC, SiC-Tb-Au-Fe-SiC, and phthalocyanine dye-bismuth-phthalocyanine dye multilayer nanofilms is experimentally studied. The photon pressure of a laser beam is shown to cause electrons to drift in the direction of beam propagation. As a result of the injection of spin-polarized electrons from the magnetic layer, a nonequilibrium magnetization arises in the nonmagnetic Bi or Au layer, which changes the magnetooptic properties of the films. In three-layer dye-bismuth-dye films, the photon pressure of the laser radiation induces a space electron charge in the exit dye layer, which causes a drift of ionized bismuth atoms. |
