Sumario:The magnetization, electric resistivity, and magnetoresistance properties of Pd [Formula: see text] Mn [Formula: see text] Sn [Formula: see text] Heusler alloys were investigated. The Curie temperature of the parent phase, martensitic transformation temperatures, and magnetic field dependence of the martensitic transformation temperatures were determined. The magnetoresistance was investigated from 10 to 290 K, revealing both intrinsic and extrinsic magnetoresistance properties for this alloy. A maximum of about [Formula: see text] % of intrinsic magnetoresistance under 90 kOe and of about [Formula: see text] % of extrinsic magnetoresistance under 180 kOe were obtained. Moreover, the thermal transformation arrest phenomenon was confirmed in the Pd [Formula: see text] Mn [Formula: see text] Sn [Formula: see text] alloy, and an abnormal heating-induced martensitic transformation (HIMT) behavior was observed.
