摘要：

Mn-Al thin films with the composition of 31-68 at.% Mn were prepared by rf magnetron sputtering at various substrate temperature then annealing in vacuum. Effects of the chemical composition, substrate temperature and annealing temperature on the magnetic properties of Mn-Al films have been investigated. The analysis of x-ray diffraction and magnetic measurement indicate that tau-phase was synthesized at a composition range of 40-60 at.% Mn. However, the formation of large amount of tau-phase occurred at Mn-50-Al-50 films, which have a high coercivity up to about 3000 Oe and a fairly large saturation magnetization of about 420 emu/cc.
