Title: Magnetic structure and phase transition of Ni 2Mn 1.48Sb 0.52 magnetic shape memory compound

Here, a comprehensive study of the structural and magnetic properties of the Ni 2Mn 1.48Sb 0.52 compound is presente using neutron diffraction and magnetic measurements. It is found that Mn atoms on 4a and 4 sites are ferrimagnetic coupled in the austenitic phase. At 300 K, the magnetic moments of Mn (4a) an Mn (4b) are determined to be 2.72(3) μ B and -2.67(5) μ B, respectively. From 260 K to 4 K, the compound is in martensite phase and the magnetic moments of Mn (2a), Mn (2f), Mn (2b), Mn (2e) at 4 K ar 2.2(5) μ B, 2.3(5) μ B, -2.1(5) μ B, and -2.6(5) μ B, respectively.
