Abstract
The structural and magnetic properties of Heusler alloy Ni 46Mn41In13 were studied by magnetization and X-ray powder diffraction measurements in the 4.5350K temperature range and in magnetic fields up to 5 T. The alloy undergoes martensitic transformation from a L21-type cubic structure with ac = 0.600nm at 293K to a six-layered monoclinic (6M) structure in the transition temperature of 160230 K. The lattice parameters for the 6M structure were estimated to be am = 0.441 nm, bm = 0.557 nm, cm = 1.30 nm, αm = 90.0°, βm = 94.0°, and γm = 90.0° at 75 K. In this transformation from the L21 to 6M structures, the cell volume contracts by 0.34% at 8K. In addition, we observed the magnetic field-induced reverse transformation of this alloy.
