Abstract

The effect of cobalt addition to Ni50Mn37Sn13 (numbers indicate at.%) and the influence of Ni excess on phase transitions in Ni50+xMn37-xSn13 ferromagnetic shape memory alloys were studied by means of differential scanning calorimetry and magnetization measurements. The results obtained revealed that the martensitic and magnetic phase transition temperatures strongly depend on whether Co is substituted instead of Ni or Mn. Magnetic properties of Ni50+xMn37-xSn13 have complex character. The martensitic transition temperature in these alloys shows a tendency to increase with increasing Ni excess.
