Abstract
The stress dependent magnetic parameters of epitaxial garnet films were measured. Lattice distortion was found to have a significant effect on the uniaxial anisotropy constant and on the domain wall parameters. Although coercive properties are also expected to be sensitive to mechanical stress. this effect was not revealed because of the different individual properties of the samples. A method is suggested for determining the stress dependence of coercivity, measured on the same sample. Present results show the primary effect of material structure on the domain wall coercive field. The effect of modifying magnetic parameters is weaker, though it also leads to a change in coercivity.
