Abstract
Deposited on the glass substrate by direct current (dc) magnetron sputtering, the Fe-Cu-Mn thin film consisting of Fe nanoparticles embedded in a Cu matrix was treated by vacuum annealing. The effects of Mn doping and annealing temperature on the structure, magnetic properties, and magnetoresistance were investigated. The as-deposited films had flat, compact surfaces and face-centered cubic (fcc) structure. The grain size of Fe increased with the annealing temperature. With the Mn doping, the size increased first and then decreased. The Mn content exists in an amorphous state in the nanocomposite films, and it is homogeneously distributed between the Fe nano-grains, which increase grain growth and obtain isolated Fe particles with uniform size. Not all of the Mn atoms diffuse into the nano-sized Fe particles until the Mn content reaches 10 at.%. The easy magnetization direction of the Fe-Cu-Mn films is in plane rather than out of plane. Coercivity, remanent magnetization, remanence ratio, and hysteresis losses are associated with increasing content of Mn in the samples. As Mn doping occurs, the magnetoresistance (MR) of the Fe-Cu film is reduced and the best temperature corresponding to the maximum value of MR is ∼350 °C.
