采用分子束外延（MBE）方法在MgO（111）、Al 2 O3（001 c）和熔融石英衬底上生长CrPt 3和MnPt 3合金薄膜。在熔融石英、Al 2 O3和MgO上的（111）取向CrPt 3薄膜表现出单轴各向异性，其Ku值分别为1.9×106、0.9×106和−1.0× 106 erg/cm 3。熔融石英和MgO上的MnPt 3的Kuof分别为-0.8 × 106和-0.2 × 106 erg/cc。CrPt 3和MnPt 3在熔石英上的磁弹性各向异性贡献了磁弹性各向异性。
CrPt3and MnPt3alloy films were grown onto MgO(111), Al2O3(001c), and fused quartz substrates by MBE method. The (111) oriented CrPt3films on fused quartz, Al2O3, and MgO exhibited uniaxial anisotropy Kuof 1.9×106, 0.9×106, and −1.0×106erg/cm3, respectively. The MnPt3on fused quartz and MgO exhibited Kuof −0.8×106and −0.2×106erg/cc, respectively. The Kuof CrPt3and MnPt3on fused quartz was found to be the contribution of the magneto-elastic anisotropy.
