Notes:
Amorphous alloy thin films of (Co95Zr5)100−xDyx with a well-defined in-plane uniaxial anisotropy Ku were prepared by rf sputtering. The saturation magnetization, Ku, and the coercive field were studied as a function of temperature and for the composition range 4≤x≤20. Ms could be fitted by the molecular-field model, Ku interpreted by a single-ion anisotropy process, and Hc by a model of Alben, Becker, and Chi [J. Appl. Phys. 49, 1653 (1978)]. At low temperatures (T≤50 K) and for the whole concentration range a new type of aftereffect is observed, the main characteristic of which is described.
