Аннотация

X-ray and magnetometry methods are used to show that, during magnetron sputtering of Dy/Co periodic multilayer systems, the DyCo2 and DyCo3 intermetallics form. The main reason for the phase formation of various intermetallics is the structural state of buffer layer, namely, its crystalline and amorphous state in the case of crystalline and glass substrate, respectively.
