摘要

Two series of perpendicular exchange coupled composites (ECC) films are prepared by dc magnetron sputtering, FePt(5)/[Co(0.2)/Pt(0.3)] _N (ECC-I-N) and FePt(5)/[Co(0.2)/Pt(0.6)] _N (ECC-II-N), respectively. Structure analyses reveal the epitaxial growth on (001) oriented L1 ₀ FePt island-like grains of [Co/Pt] _N with (200) orientation. Coercivity H _C and remanent coercivity H _CR of both series samples decrease sharply compared to FePt, with the increase of the thickness of [Co/Pt] _N. The angular dependence of H _CR shows excellent angular tolerance.
