Properties of Molybdenum‐Permalloy Films

Ternary alloy films were produced by variable‐ratio sequential and simultaneous two‐source evaporation under conditions comparable to those of technical Permalloy film evaporation. Intrinsic film properties measured at Mo concentrations up to 6%–8% indicated reductions of M, Hc, Hk, and dispersion. At high Mo concentrations, oblique incidence produced strong anisotropies. Crystallite dimensions were substantially less than in normal Permalloy films, and increased resistance to annealing was observed.
