摘要
A series of Fe-Pt based alloy films were deposited on glass substrates by DC magnetron sputtering. It is found that the Fe3Pt and FePt3 phases appear in Dy-addition films at first and then a composition reaction Fe3Pt + FePt3 -> FePt occurs at 500 degrees C as annealing time increase. It suggested that Dy element can restrain the fct phase forming but help to form Fe3Pt and FePt3 phases. Coercivity and remanence ratio of DyxFe50-xPt50 alloy films annealed at 500 degrees C for 200 h achieve the maximum 11kOe and 0.89 as x = 1.5, respectively.
