Abstract

An extended method for anisotropy field measurements has been developed using a vector vibrating sample magnetometer (VSM). The technique, which relates the switching of particles nearly perpendicular to an applied field to the sample anisotropy, is suitable for magnetic media that contain orientated particles. Results measured as a function of angle are extrapolated to 90° for an improved measure of anisotropy field. In plane properties have been investigated for a series of four advanced double coated metal particle (MP) tapes. The results show that the in plane anisotropy field is related to the magnetic coating thickness, as a result of changes in magnetostatic interactions between the particles with thickness.
