Abstract

The effect of heat treatment in air atmosphere was investigated on an epitaxially grown magnetic garnet film. The value of the uniaxial anisotropy field decreased by the annealing, but its exponential increase with decreasing temperature was not affected. The annealing up to 1200degreesC had practically no influence on other magnetic parameters, including the domain-wall pinning field, H-p, and its temperature dependence. The fact that H-p is independent of the heat treatment, in spite of the strong annealing dependence of the anisotropy field values, was explained by the appropriate modification of the characteristic parameters of the defects systems present in the sample.
