TI  - MAGNETOCALORIC EFFECT AROUND CURIE TEMPERATURE IN Ni50-x CuxMn38Sn12B3 SHAPE MEMORY RIBBONS
AB  - The magnetocaloric effect in Ni50-xCuxMn38Sn12B3 ribbonsdepending on the Cu substitution (x= 0, 1, 3) was investigated around the Curietemperature. The purpose of the present study was to analyze the magnetocaloriceffect around a second order phase transition (around the Curie temperature) whichhas a smaller thermal hysteresis compared to a first order phase transition(Martensitic transition). The Curie temperature of the ribbons shifted to highertemperatures with increasing Cu content. A conventional magnetocaloric effect(MCE) was observed around the Curie temperature when the ribbons are subjectedto a magnetic field change of 5 T. The magnetic entropy changes were calculatedbased on the isothermal magnetization M(H) data using thermodynamic Maxwellequation. The highest magnetic entropy change and the refrigerant capacity wasobtained for the x=1 ribbon.
