Magnetization Of Thin Films Under Oblique Field Conditions

Abstract

Magneto-optical measurements have been made of a single layer film of TbFeCo and a multilayer PtCo film both with perpendicular anisotropy. Magnetizing fields were applied at angles in the range 9 = 0" to 60" with respect to the normal. Switching fields and the time dependence of magnetization were measured. The variations of intrinsic switching field as functions of l/cos9 are shown in Fig. 1.
