Abstract
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.
