Multiple magnetic transitions and magnetocaloric effect in Gd1-xSmxMn2Ge2 compounds
Pramod Kumar, Niraj K. Singh, K. G. Suresh +2
Magnetic and magnetocaloric properties of polycrystalline samples of Gd1-xSmxMn2Ge2 have been studied. All the compounds except GdMn2Ge2 show re-entrant ferromagnetic behavior. Mul…
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…
Heat capacity and magnetoresistance in Dy(Co,Si)2 compounds
Niraj K. Singh, K. G. Suresh, A. K. Nigam +1
Magnetocaloric effect and magnetoresistance have been studied in Dy(Co1-xSix)2 [x=0, 0.075 and 0.15] compounds. Magnetocaloric effect has been calculated in terms of adiabatic temp…
