Heat capacity and magnetocaloric effect in polycrystalline Gd1-xSmxMn2Si2
Pramod Kumar, Niraj K. Singh, K. G. Suresh +2
We report the magnetocaloric effect in terms of isothermal magnetic entropy change as well as adiabatic temperature change, calculated using the heat capacity data. Using the zero…
Role of coexisting ferromagnetic and antiferromagnetic phases on the magnetocaloric effect in metamagnetic Tb2Ni2Sn
Pramod Kumar, Niraj K. Singh, K. G. Suresh +1
We report the anomalous magnetocaloric behavior in the polycrystalline compound Tb2Ni2Sn. The magnetization measurements show that this compound shows multiple magnetic transitions…
Correlation between magnetism and magnetocaloric effect in RCo2-based Laves phase compounds
Niraj K. Singh, K. G. Suresh, A. K. Nigam +3
By virtue of the itinerant electron metamagnetism (IEM), the RCo2 compounds with R=Er, Ho and Dy are found to show first order magnetic transition at their ordering temperatures. T…
Effect of Ge substitution for Si on the anomalous magnetocaloric and magnetoresistance properties of GdMn2Si2 compounds
Pramod Kumar, Niraj K. Singh, K. G. Suresh +2
The effect of Ge substitution on the magnetization, heat capacity, magnetocaloric effect and magnetoresistance of GdMn2Si2-xGex (x=0, 1, and 2) compounds has been studied. The magn…
Effect of Y substitution on the structural and magnetic properties of Dy1-xYxCo5 compounds
Debjani Banerjee, K. G. Suresh, A. K. Nigam
Structural and magnetization studies were carried out on Dy1-xYxCo5 [x = 0, 0.2, 0.4, 0.6, 0.8, 1] compounds which crystallize in the hexagonal CaCu5-type structure. Lattice parame…
