Abstract

The coercivity of epitaxial magnetic garnet films measured by the domain-wall-oscillation methods depends on the size of the sample. It is shown that this effect is characteristic of only the wall-oscillation method. A direct, empirical correlation was found between the mechanical stresses of the sample and its magnetic parameters. It was concluded that any effect of a modification of mechanical stresses resulting from cutting of the sample can be disregarded as a possible contribution to the effect of sample size on coercivity.
