Abstract

A UNIAXIAL magnetic anisotropy is observed in thin nickel–iron films which have been deposited, in the presence of a uniform magnetic field, on to a heated glass substrate supported in vacuum. Macdonald1 and Finegan and Hoffman2 have reported that both nickel and iron films can be in a state of anisotropic stress. Nickel, for example, can contain an anisotropic planar compression of about 5 × 108 dynes/ cm.2. Such an anisotropic stress, if present in the nickel–iron films, could contribute to the magnetic anisotropy both directly through the magnetostriction, and indirectly through stress-induced iron-pair directional ordering, as suggested by Zener3. Several authors4–6 have used such stresses in explaining, at least in part, the magnetic anisotropy of thin nickel–iron films. However, no direction observations of the stress in evaporated nickel–iron films have been reported.
