Paper Abstract

Various relations are presented between a number of process variables and the resultant properties of transition metal-rare earth films. In particular the bias voltage, target voltage and argon gas pressure are related to the film coercivity, compensation temperature, anisotropy and film thickness. The domain size obtained on writing in these films with a laser is given as a function of write field, anisotropy, coercivity, film thick-ness, bias, and laser pulse width. Domains as small as 0.4 μm are reported. The trends observed are explained.
