AbstractDomain-wall scattering in a FePd-ordered alloy film with strong perpendicular magnetic anisotropy has been investigated using magnetoresistance measurements on a whole hysteresis loop and as a function of temperature. A strong correlation between the hysteretic behavior of the resistivity due to domain walls and the magnetization process is found. The data are well described by a spin-dependent electron scattering model. This study establishes that this phenomenon can be used to identify directly magnetization reversal dynamics and electronic transport characteristics in materials with high magnetic anisotropy.
