摘要：

Co80Pt20 thin films (0.125-1.0 mum) were galvanostatically (10-50 mA/cm(2)) electrodeposited onto Cu(111) oriented seed layers. Coercivity (3-6.1 kOe), saturation magnetization (778-832 emu/cm(3)) and uniaxial magnetic anisotropy (0.82 x 10(7)-1.02 x 10(7) erg/cm(3)) in the perpendicular direction increase both with current density and film thickness due to a combined effect of decrease in the porosity and increase in the crystallinity of the films.
