| Abstract: | X-ray powder diffraction and magnetization measurements were done on the magnetic shape memory alloys Ni2Mn1+xIn1−x. On the basis of the results, the magnetic phase diagram was determined for Ni2Mn1+xIn1−x alloys. Magnetization measurements make clear that the excess Mn atoms, which substitute for In sites, are coupled ferromagnetically to the ferromagnetic manganese sublattices. A magnetic phase diagram of Ni2Mn1+xIn1−x alloys is discussed qualitatively on the basis of the interatomic dependence of the exchange interactions. |
