Magnetic phase diagram of Heuselr alloys Pd2Mn1+xSn1−x

► Magnetic phase diagram was first established in Pd2Mn1+xSn1−x alloy system. ► The magnetic phase diagram of Pd2Mn1+xSn1−x is similar to that of Ni2Mn1+xSn1−x shape memory alloys. ► It was suggested that Pd2Mn1+xSn1−x system has a possibility to be metamagnetic shape memory alloys.
