Abstract

The magnetic and electrical properties on magnetic Heusler alloy Ni50 Mn36 Sn14 were studied in magnetic fields up to 18 T in 4.2-270 K temperature range. It was found that at the vicinity of 160 K the resistivity jump of 46% is accompanied by the magnetic phase transition. Furthermore, the large magnetoresistance effect of 50% by the magnetic field induced magnetic phase transition was observed.
