摘要
A study of the magnetic properties of (FexCo100-x)(3)Pt (0 less than or equal to x less than or equal to 50) ternary alloy thin films in conjunction with the structure has been carried out. At x less than or equal to 10, the existence of hcp (m-DO19) phase is realized. This m-DO19 phase is found to exhibit the large perpendicular magnetic anisotropy (K-per) (similar to10(7) erg/cc). There is a maximum in K-per at about x = 10. The K-per is found to decrease with x (x > 10), which is correlated with the structural transformation. (C) 2004 Elsevier B.V. All rights reserved.
