摘要：

High epitaxial (001)-, (110)- and (111)-oriented Ni ferromagnetic thin films were coherently grown on Pb(Mg1/3Nb2/3)(0.7)Ti0.3O3 (PMN-PT) (001), (110) and (111) substrates by magnetron sputtering. Reciprocal space mapping (RSM) results indicate that all of these films are partially relaxed. The mechanism of strain-induced magnetic anisotropy of these epitaxial thin films has been investigated in detail. The easy axis is induced toward out-of-plane (OOP) due to compressive strain, while the hard axis is along in-plane (IP) owing to tensile strain. (111)- and (110)-oriented Ni thin films show the strongest and the weakest magnetic anisotropy, respectively. The strain-induced magnetoelastic energy for (001)-oriented Ni thin film increases its anisotropic field and decreases its total free energy resulting in an enhanced magnetic anisotropy comparing with (110)-oriented one. The remarkable variation of magnetization in high epitaxial Ni thin film system reveals that the magnetic anisotropy can be modulated by changing the biaxial strain.
