项目摘要

1) The perpendicular magnetic anisotropy energy in the ferromagnetic/nonmagnetic metallic multilayrs were investigated calculating the electronic structures by LMTO-ASA method within the framework of the local-density-approximation, for X/Co (X= Pd, Pt, Cu, Ag, Au, Ni) and X/Fe (X=Ag, Au, Ni) systems. We have found that the general tendency of the perpendicular magnetic anisotropy energy (MAE) in these systems are well explained by first-principles calculations. The thickness of Co (ferromagnetic) layr dependence and the strain dependence of the MAE were also investigated.2) The magnetic properties of rare-earth and 3d transition metal compounds are enhanced by the addition of N,C or B.We have calculated the electronic charge density maps and the spindensity maps of GdFe_<12>, GdFe_<12>N,Gd_2Fe_<17> and Gd_2Fe_<17>N_3 by the FLAPW method and clarified the microscopic origin of the strong uniaxial magnetic anisotropy energy due to the addition of N or C.It was also found that the addition of N is most effective to enhance the magnetism of these compounds.3)We have also calculated the MAE due to the spin-orbit coupling of 3d transition metal itself for YCo_5, Y_2Co_7, YCo_3 and Y_2Co_<17> by the LMTO method including the spin-orbit coupling term.4)We have also performed the preliminary calculation of the magneto-optical (Kerr) effect by the LMTO method for hcp-Co, fcc-Co, and ferromagnetic/nonmagnetic metallic multilayrs Fe (nML) /Au (nML) (n=1,2,3,4) and TM (1ML) /X (2ML)(TM=Mn, Fe, Co ; X=Pd, Pt, Ag, Au) systems.5)We have also performed the first principles calculations to predict theoretically new half-metallic compounds to realize the half-metallic/nonmagnetic multilayr.
1)在局域密度近似下,采用LMTO-ASA方法计算了X/Co(X= Pd,Pt,Cu,Ag,Au,Ni)和X/Fe(X=Ag,Au,Ni)体系的电子结构,研究了铁磁/金属多层膜的垂直磁各向异性能.我们发现,这些系统中的垂直磁各向异性能(MAE)的一般趋势很好地解释了第一性原理计算。2)N、C或B的加入增强了稀土和3d过渡金属化合物的磁性,计算了GdFe_2<12>、GdFe_<12>N、Gd_2Fe_3和<17>Gd_2Fe_<17>N的电子电荷密度图和自旋密度图。结果表明,N和C的加入对提高合金的单轴磁各向异性能有很大的作用,3)采用包含自旋轨道耦合项的LMTO方法计算了YCo_5,Y_2Co_7,YCo_3和Y_2Co_4中由于3d过渡金属自身自旋轨道耦合引起的MAE; 4)采用LMTO方法对hcp-Co,fcc-Co<17>,以及铁磁/非金属多层膜Fe(nML)/Au(nML)(n= 1,2,3,4)和TM(1ML)/X(2ML)(TM=Mn,Fe,Co ; X=Pd、Pt、Ag,Au)体系。5)我们还进行了第一性原理计算,从理论上预测新的半金属化合物,以实现半金属/多层的。
