Effect of misorientation on growth anisotropy in [111]-oriented garnet films

Abstract

Phenomenological anisotropy constants have been measured in three garnet bubble films with their surface normal slightly misoriented from the crystallographic [111] direction. A tilted magnetic easy axis is found from measurements of homogeneous nucleation and bubble collapse in the presence of in-plane fields. An in-plane anisotropy is also found whose axes do not in general lie either normal to or in the easy-axis tilt plane. These results are shown to be consistent with a phenomenological growth anisotropy model which includes the film plane misorientation. © 1974 American Institute of Physics.
