Abstract
We report here (Co93Cr7)-P-Pt thin films with coercivity higher than 2600 Oe at the thickness of 180 Å (M r·t value of 0.9 memu/cm2) even when they were deposited without substrate heating and bias voltage. The effects of the film composition and the magnetic layer thickness were studied. The coercivity of Co-Cr-Pt film increased with addition of P up to 12 at.%. With addition of P, the degree of Co (0002) texture was reduced and the grain size of films became more uniform. These effects appear to be associated with the coercivity increase
