S. Villain et al., SURFACE-ROUGHNESS AND COMPOSITION EFFECTS ON THE MAGNETIC-PROPERTIES OF ELECTRODEPOSITED NI-CO ALLOYS, Journal of magnetism and magnetic materials, 158, 1996, pp. 274-275
The dependence of the local surface roughness sigma of Ni-Co alloy fil
ms on their composition x is reported. The coercive field H-c and the
remanence M(r) are both sensitive to sigma and x. Surface oxidation an
d domain walls explain the effect of sigma, and magnetostriction expla
ins the effect of x.
