摘要：

Compositional separations in CoCrTa perpendicular magnetic thin films deposited at different substrate temperatures are observed using a transmission electron microscope equipped with an imaging Filter. Quantitative elemental maps of cobalt and chromium are constructed for specimens deposited at substrate temperatures of 25, 170 and 230 degrees C. Both intragrain and intergrain chromium segregation are observed at elevated substrate temperatures. High coercive force is obtained for specimens with extensive chromium segregation at the grain boundaries.
