A. Ghotbi Varzaneh,Parviz Kameli,T. Amiri,Krishna K. Ramachandran,Arthur Mar,I. Abdolhosseini Sarsari,Jing-Li Luo,T. H. Etsell,Hadi Salamati +8 more
TL;DR: A series of Heusler phases Ni47Mn40Sn13−xCux (x = 0, 0.5, 1, 1.25), which are magnetic shape-memory alloys, has been synthesized by mechanical alloying (MA) and characterized by X-ray diffraction, differential scanning calorimetry, and DC magnetization measurements as mentioned in this paper.
Journal ArticleDOI
Inverse-direct magnetocaloric effect crossover in Ni47Mn40Sn12.5Cu0.5 Heusler alloy in cyclic magnetic fields
A. G. Gamzatov,A. M. Aliev,A. Ghotbi Varzaneh,Parviz Kameli,I. Abdolhosseini Sarsari,Seong-Cho Yu +5 more
TL;DR: In this article, the magnetocaloric effect of Ni47Mn40Sn12.5Cu0.5 Heusler alloy in cyclic magnetic fields is investigated. But the results of direct studies of the magnetocoric effect (MCE) of the Ni47mn40sn12.6Cu0., and the results show that the MCE value near the magnetostructural phase transition depends on the rate of temperature scanning.
Journal ArticleDOI
Magnetocaloric effect in Ni47Mn40Sn13 alloy prepared by mechanical alloying
TL;DR: In this article, structural, microstructural and magnetocaloric properties of Ni47Mn40Sn13 magnetic shape memory alloy prepared by mechanical alloying (MA) technique were reported.
Journal ArticleDOI
Effect of heat treatment on martensitic transformation of Ni 47 Mn 40 Sn 13 ferromagnetic shape memory alloy prepared by mechanical alloying
TL;DR: In this paper, an attempt has been made to synthesis of the nanostructured Ni47Mn40Sn13 ferromagnetic shape memory alloy by ball milling of Ni, Mn and Sn powder mixture.
