Abstract

The origin of the large perpendicular magnetic anisotropy (0.5-1×10-6 erg/cm3) of Ni-polyethelene coevaporated films has been studied. It is indicated that the anisotropy can be very well explained by uniaxial anisotropy induced by the large tensile stress (1-3×1010 dyn/cm2) through the inverse magnetostrictive effect. Other factors, such as magnetocrystalline or shape anisotropy, produce little effect on the perpendicular anisotropy of the films.
