We report spin-orbit torques (SOT) in L10-ordered perpendicularly magnetizedFePt single layer, which is significantly influenced by disorder. Recently,self-induced SOT in L10-FePt single layer has been investigated, which isascribed to the composition gradient along the film normal direction. However,the determined mechanisms for magnetization switching have not been fullystudied. With varying growth temperatures, we have prepared FePt single layerswith same thickness (3 nm) but with different disordering. We have found thatnearly full magnetization switching only happens in more disordered films, andthe magnetization switching ratio becomes smaller as increasing L10 ordering.The method for deriving effective spin torque fields in the previous studiescannot fully explain the spin current generation and self-induced SOT inL10-FePt single layer. Combined with Magneto-Optical Kerr Effect microscopy andanomalous Hall effect measurements, we concluded that the disorder shoulddetermine the formation of domain walls, as well as the spin currentgeneration.
