Abstract：Co2MnAl Heulser films have been prepared by a magneto co- sputtering method. The effect of substrate temperatures (23-500 ℃) on the crystal structure, magnetic properties and surface roughness of Co2MnAl films were systematically investigated. It was confirmed that the Co2MnAl film prepared at 300 ℃ showed an optimized B2 crystal structure. The film has the maximum of saturated magnetization and a very small roughness. The study indicates the coercivity of Co2MnAl films could be regulated from 400 to 2 785 A/m by varying the substrate temperatures.
