摘要：
We report the observation of perpendicular magnetization in ultrathin amorphous Fe70B30/Ag multilayer films by means of Mossbauer spectroscopy. In contrast to other techniques that require the application of an external magnetic field, the field-free condition of Mossbauer spectroscopy allowed the intrinsic magnetic properties of ultrathin films to be studied. Our study indicates that at elevated temperatures an external field may easily alter the spontaneous magnetization in an ultrathin film with very small effective anisotropy and thus obscure its intrinsic magnetic properties. By virtue of the microscopic probing capability of Mossbauer spectroscopy, the surface magnetic properties of thin amorphous Fe70B30 films have also been studied.
