Abstract
The Ni50Mn35In12Bi3 and Ni47Mn35In15Bi3 belongs to Heusler alloys family: X2YZ (where X and Y are typically transition elements or lanthanides while Z atom is from group III or IV) and attracted much interest because of their magnetic and transport properties. The structural, magnetic, magnetocaloric and magnetotransport properties of Ni50Mn35In12Bi3 and Ni47Mn35In15Bi3 has been studied using room-temperature X-ray diffraction (XRD), and magnetization measurements. The results of these measurements will be presented. The Ni47Mn35In15Bi3 shows magnetocaloric effects in the vicinity of its magnetostructural transition (MST) and it’s Curie temperature (Tc=291K) at 100 Oe filed. Magnetic entropy change and magnetoresistance has been calculated for these alloys and will be presented.
