Abstract

Single crystal Heusler alloy Ni₂MnAl thin films have been grown by molecular beam epitaxy on GaAs (0 0 1) using Sc_0.3Er_0.7As interlayers. The effect of growth temperature on the structural and magnetic properties was studied. Films grown at lower temperatures were non-ferromagnetic with a B2-like crystal structure; while higher growth temperature (400 °C) resulted in ferromagnetic films suggesting a L2₁-like structure. Exchange bias was detected in Ni₂MnAl/Ni₂MnGe (ferromagnetic) and Co/Ni₂MnAl bilayers, suggesting that the Ni₂MnAl films grown at 180 °C (in the B2-like structure) are antiferromagnetically ordered.
