摘要：

The development of compositional inhomogeneities in sputtered Co-22 at.% Cr films is studied as a function of substrate temperature using the spin-echo Co-59-NMR technique. It is observed that a highly Co-rich component grows as the substrate temperature increases from 30-degrees-C to 400-degrees-C. The Cr content of the Co-rich part in the film deposited at 400-degrees-C is estimated to be as low as 5-7 at.%. The results are consistent with the appearance of a clearly striped compositional microstructure which suggests compositional separation.
