Popis: | Annealing behavior of magnetic anisotropy in LPE garnet films are investigated. There exists a good correlation between the activation energy for the decreasing process of K u and the difference between the ionic radii of the constituent rare earth ions. It implies that this difference is the physical origin for the nonuniform distribution of the rare earth ions which results in the presence of the uniaxial anisotropy. Further, the anisotropy with cubic symmetry is enhanced by the nonuniform distribution. |
