Role of replacement of Sb with Al in the phase transformation of Ni-Mn-Sb alloys
TL;DR: Ferromagnetic shape memory alloy with composition Ni50Mn34Sb8Al8 was prepared and its structural transformation temperatures were determined as mentioned in this paper, the replacement of Sb with Al in this alloy led to increase in transition temperature but more interestingly, the low temperature magnetic behavior shows spin glass type nonergodic behavior, in contrast to simple ferromagnetic like other similar alloys.

Magnetorheological Payne effect in bidisperse MR fluids containing Fe nanorods and Fe3O4 nanospheres: a dynamic rheological study
TL;DR: In this article, the authors performed detailed nonlinear magnetorheological properties of three MR fluids (10 vol%) containing isotropic Fe3O4 and anisotropic Fe-nanorods under both small and large amplitude oscillatory flow.
Journal ArticleDOI
Crystal Structure and Dielectric Properties of Microwave Ceramics CaLa(CaM)O 6 [M = Nb, Sb]
TL;DR: In this article, the dielectric properties of perovskite oxides CaLa(CaM)O6 [M = Nb, Sb] synthesized by the solid-state reaction technique have been studied in the microwave and radio frequency range.
Journal ArticleDOI
Electronic and magnetic properties of disordered AuCr alloys: A first-principles study
TL;DR: In this article, the electronic structure and magnetism in the disordered alloy AuCr, for compositions in which the Cr concentration is less than 30%, were studied using a first principles density functional based augmented space recursion technique generalized to study non-collinear magnetic structures.
Journal ArticleDOI
Compositional invariance of magnetocaloric effect near room temperature in Ni–Mn–Sb–Al systems
TL;DR: In this article, structural transformation, magnetism and magnetic entropy change in the vicinity of structural and magnetic transformation has been performed in the Ni2Mn1.36Sb0.64 by substituting Sb with a large amount of Al. This substitution enhanced the transformation temperature close to room temperature and also made it less sensitive to the variation in composition.
