Abstract

For identifying the magnetic alloying effect on the magnetic anisotropy in the magnetic ultrathin films, the spin-reorientation transition was studied by preparing the ultrathin Fe_xNi_1-x and Co_xNi _1-x alloy films on Cu(1 0 0) with variations of coverage and alloy concentration x. The comparison between Fe_xNi_1-x/Cu(1 0 0) and Co_xNi_1-x/Cu(1 0 0) shows that the modification of the critical thickness for the spin-reorientation transition by the alloy concentration x for Fe is 1.35 times larger than modification by Co. The evolution of spin-reorientation transition in this Ni-dominant films could be mainly traced back into the local behavior of d-electrons in impurities and host element, corrected with the charge transfer of d-electrons between them.
