Abstract
Quaternary (CoCrPt)100xNbx/Cr bilayer thin films have been sputter-deposited and their magnetic and
microstructural properties determined as a function of niobium content and thermal annealing. Coercivity,
magnetisation, crystallography and magnetic interactions are shown to be dependent on composition and annealing
conditions. Large coercivity increases and reduced magnetisations and intergranular interactions are obtained in
annealed crystalline samples. As-deposited amorphous samples and those crystallised during annealing exhibit low
coercivity. The observed properties are explained in terms of composition and crystallographic orientation on
deposition and by a redistribution, diffusion and oxidation of elements on annealing.
