Abstract

An array of 42 μm square, 3μm thick garnet particles was discussed. It was found that the strong crystalline uniaxial anisotropy of these particle resulted in the stable remanent state being single domain with magnetization parallel to the film normal. The analysis showed that the small HSW were not attributed to shape anisotropy but was consistent with smooth, localized reductions in the crystalline anisotropy caused by defects in either the particles or the substrate.
