Abstract

The mechanism of switching of uniaxial, single domain, single crystalline epitaxial garnet particles on a two-dimensional square array was investigated, and the reason for the wide distribution of switching fields was studied. In spite that the particles were found very uniform, the existence of soft magnetic defects, not connected to visible crystalline or manufacturing defects of the material, was found to be responsible for the broad distribution of the switching field, Hc = 280±85Oe, as measured on a large number of individual particles. Very good quantitative correlation was found between the strength of the these defects and the switching field.
