Bilayer films with Fe65Co35 main layer/underlayer structure were successfully prepared by magnetron sputtering on different underlayers Co93Fe7 and Fe. X-ray diffraction XRD analysis and magnetic measurements show that Fe65Co35 thin films deposited on different underlayers have different textures. Moreover, the soft magnetic properties of Fe65Co35 thin films with 200 texture are better than that of Fe65Co35 thin films with 110 texture. Investigation of several typical samples by conversion electron Mssbauer spectrum CEMS reveals that the vector of magnetization of Fe65Co35 thin films have a little deviation from the film plane, and the deviation from the film plane of Fe65Co35 thin films with 110 texture are bigger than that of Fe65Co35 thin films with 200 texture. Further study exhibits that this phenomenon is caused by the interface anisotropy induced by magnetoelastic anisotropy at the interface between Fe65Co35 thin film and underlayer.
