Interplay of austenite and martensite phase inside martensite transition regime and its role on magnetocaloric effect and magnetoresistance in Ni-Mn-Sn based Heusler alloy

Autor: T. Chabri, T. K. Nath, A. Venimadhav

Publikováno v: Intermetallics. 102:65-71

The first order martensite transition has been observed clearly through magnetic, electronic- and magneto-transport studies in Ni45Mn44Sn11 disordered ferromagnetic shape memory Heusler alloy. The alloy also shows second order ferromagnetic → param

Magnetic and lattice entropy change across martensite transition of Ni-Mn-Sn melt spun ribbons: Key factors in magnetic refrigeration

Autor: A. Venimadhav, T. K. Nath, T. Chabri

Publikováno v: Journal of Magnetism and Magnetic Materials. 466:385-392

Ni 45 Mn 44 Sn 11 melt spun ribbons have been prepared by melt spinning technique. A single austenite L2 1 phase with lattice constant 5.945 A is confirmed at room temperature. The first order martensite transition is observed from calorimetric, elec

Effects of transitional hysteresis on the large magnetocaloric and magnetoresistance properties of Ni-Mn-Co-Sn Heusler alloy

Autor: T. K. Nath, S.K. Chatterjee, S.A. Mollick, T. Chabri, Devajyoti Mukherjee, Anjan Barman

Publikováno v: Journal of Alloys and Compounds. 863:158485

Ni-Mn-Co-Sn based Heusler alloys have drawn immense attention lately due to their significant magnetocaloric (MC) and magnetoresistance (MR) properties near their first-order magneto-structural martensite transformation (MT). Here, we have studied th

Field induced martensitic phase transition in nonstoichoimetric Ni45Mn44Sn11 Heusler alloy

Autor: T. Chabri, A. Venimadhav, T. K. Nath

Publikováno v: AIP Conference Proceedings.

Nonstoichiometric high-Mn content Mn45Ni44Sn11 ferromagnetic shape memory alloys (FSMAs) were prepared by arc melting technique. First order transition near the martensitic transition (austenitic → martensitic) has been observed from magnetization,
