Abstract: | This paper reports on the results of experimental investigations of the magnetic properties of a trilayer system that consists
of high-coercive polycrystalline and low-coercive amorphous magnetic Co-P layers and a nonmagnetic amorphous Ni-P interlayer.
It has been established that the coercive force and the bias field of the hysteresis loop of the low-coercive layer undergo
anomalous changes in the range of small thicknesses of the hard magnetic layer. In the same range of thicknesses, a magnetic
aftereffect is found to manifest itself, which is unusual for this type of magnetic structures. The observed features are
associated primarily with the kinetics of formation of a crystal structure of the high-coercive layer. |
