Photoinduced polarization-dependent change in the domain structure of an iron garnet film
Sokhatskii V. P., Kovalenko V. F.
It was found that the domain structure of a Bi-containing iron garnet film at room temperature changes under the action of linearly polarized light. The accompanying change in the magnitude of the magnetization of the film depends on the intensity and the orientation of the polarization plane of the irradiating light. The effect is associated with the photoinduced deformation produced in the crystal lattice by polarization-sensitive charge transfer on magnetically anisotropic impurity centers. © 1995 American Institute of Physics.
