摘要：

We examined the possible occurrence of compositional separation (CS) in hcp Co-Ru alloy magnetic films. Using spin echo Co-58 NMR and transmisson electron microscopy, we found that CS, which produces a Co-rich component (almost-equal-to 10 at.% Ru), occurs in sputtered Co- almost-equal-to 33 at % Ru-films when substrate temperature is elevated to 400-degrees-C. The results suggest that the origin of CS lies in magnetically induced phase separation during film growth.
