Abstract

We study the structural and magnetic properties of Heusler based Ni50Mn50-xSbx in the composition range 5.0≤x≤25.0. The cubic phase is preserved in the range 17.0≤x≤25.0, and the presence of martensitic transformations are found in alloys with x≤15.0. In a critical composition range 12.5≤x≤10.0, the magnetic coupling in both austenitic and martensitic phases is paramagnetic, however, the presence of antiferromagnetic short-range correlations is observed in both phases. We discuss the consequences of these correlations on the behavior of the magnetic moment with respect to electronic properties.
