Abstract

These magnetic thin-film ternary alloys consist of nickel, iron and aluminum. As indicated in the table, the addition of small amounts of aluminum to the nickel-iron composition affects parameters such as anisotropy field, coercive force and dispersion. The aluminum appears in solid solution in a nominal permalloy composition. The measurements are based on a film of 9.6 Wt. % iron with the balance of the composition being nickel. The aluminum additions are by weight. The films are deposited on a heated substrate by dropping a pre-mixed powder of iron nickel and aluminum onto a hot tungsten filament in a vacuum evaporator.
