摘要：

Compositional inhomogeneity in electroless-deposited CoNiP films with perpendicular magnetic anisotropy was examined using the spin echo Co-59-NMR technique for the first time. The existence of a Co-rich component was observed which was thought to cause the formation of an hcp structure and produce high perpendicular coercivity, Hc(perpendicular-to). An increment in the Co-rich component by heat-treatment was also observed which might be an origin of the increase in Hc(perpendicular-to).
