Obliquely sputter deposited CoxNi1−x thin films were prepared under varying conditions. Here the longitudinal coercivity was used to optimise the layers with respect to geometry, layer thickness, CoxNi1−x alloy dependence, argon pressure and inpu

In this paper we will present a study of magnetic viscosity as a function of applied field of CoCrTa/Cr in-plane media. The viscosity versus applied field curves (viscosity curves) of the samples exhibit a sharp peak at remanence coercivity (Hcr). Th

A magneto‐optical (MO) Kerr tracer based on an ellipsometer was developed for studying the surface magnetic properties of thin films. This system can be used to measure the optical properties n and k, which are strongly related to the magneto‐opt
