Magnetic properties of amorphous Gd-Co-Au films
Abstract
Magnetization as a function of temperature (4.2-300°K) for the amorphous ferrimagnetic Gd-Co-Au alloys is analyzed by using a two-sublattice model. The magnetization behavior is discussed in terms of the cobalt spin value, and the intersublattice and intrasublattice exchange constants. Magnetic domain wall properties are considered in an attempt to estimate the growth-induced uniaxial perpendicular anisotropy.
