Abstract
CoNi/Pt multilayers were prepared by magnetron sputtering using Ar gas . Effects of Pt seedlayer and Ar sputtering pressure on magnetic and s tructural properties are investigated. Microstructures of multilayers were analysed using XRD and TEM. It was found that perpendicular magne tic anisotropy and coercivity increase with increasing either the thic kness of Pt seedlayer or Ar pressure. The causes of increases in perpe ndicular anisotropy and coercivity are discussed in relation to the in terface roughness, the curvature of layers and the columnar structures .
