Magnetocaloric effect in MnSi

Applied Physics Letters, 2007
The temperature dependence of heat capacity of MnSi has been measured in the presence of different values of magnetic field. When the magnetic field is applied, an appreciable adiabatic temperature change is observed in the compound. The entropy change due to isothermal change of magnetic field is found to be significant well above the ordering ...

Magnetic properties, critical behavior, and magnetocaloric effect of Nd1−xSrxMnO3 (0.2 ≤ x ≤ 0.5): The role of Sr doping concentration

Journal of Applied Physics
Magnetic characteristics, magnetocaloric effect, and critical behavior of Nd1−xSrxMnO3 compounds by Sr doping (x = 0.2, 0.3, 0.4, 0.5) were studied. All samples maintained orthorhombic structures, but the space group changed from Pnma (No.

Oscillating magnetocaloric effect

Applied Physics Letters, 2011
This Letter presents the oscillatory behavior found in the magnetic entropy change of diamagnetic materials. We show that this quantity depends on the oscillating term and, as a consequence, the magnetocaloric potential can be tuned as either inverse or normal, depending on the value of the magnetic field change.

Magnetocaloric effect of ErCo2

Journal of Magnetism and Magnetic Materials, 1999
Abstract The magnetocaloric effect was examined for ErCo 2 , which shows a first-order ferrimagnetic to paramagnetic transition at 32 K. The application of a magnetic field of 8 T causes a temperature change of 13 K under adiabatic conditions.

Magnetocaloric Effect in Dysprosium

Journal of Applied Physics, 1965
The magnetocaloric effect and magnetization of a polycrystalline ellipsoid of dysprosium were measured in magnetic fields up to 20 kOe from the temperature of liquid nitrogen to room temperature. Dysprosium exhibits both heating and cooling upon adiabatic magnetization depending on its magnetic state (ferromagnetic, paramagnetic, or antiferromagnetic ...

Magnetocaloric effect in Gd2PdSi3

Applied Physics Letters, 2000
The influence of the application of a magnetic field (H) on the temperature (T) dependence of heat capacity and isothermal magnetization has been investigated in Gd2PdSi3, a compound ordering antiferromagnetically below (TN=)21 K in zero H. Among other findings, the one to be emphasized is the observation of significant magnetocaloric effect (MCE) over
