Magnetocaloric Effect Of Ferromagnetic Particles

[1993] Digests of International Magnetics Conference, 1993
The entropy change accompanying the removal of an applied magnetic field (i.e. the magnetocaloric effect) is calculated for a system of magnetic spins independent of each other and also clustered together into independently acting magnetic particles. Mean-field-theory calculations are made for interacting, single magnetic spins and also for interacting,

Magnetocaloric Effect in a Frustrated Gd-Garnet with No Long-Range Magnetic Order.

Inorganic Chemistry, 2020
In this paper, the hyperkagome lattice of Gd spins in a garnet compound, Gd3CrGa4O12, is studied using bulk measurements and density functional computations, and the observation of large magnetocaloric effect corresponding to an entropy change, ΔSm = 45 ...

Magnetocaloric effect in DyCu2

Journal of Magnetism and Magnetic Materials, 2009
Abstract The magnetocaloric effect of the rare-earth intermetallic compound DyCu2 is explored through magnetization measurements. DyCu2 is paramagnetic at the room temperature but becomes antiferromagnetic below 27 K (Neel temperature). Strong temperature and field dependence of magnetization in DyCu2 at and around the Neel temperature lead to a ...

Magnetocaloric effect in Tb2O3 and Dy2O3 nanoparticles at cryogenic temperatures

, 2020
Magnetic refrigeration is a cooling technology based on the magnetocaloric effect, which has greater energy efficiency than conventional refrigeration, and has attracted much attention for low and room temperature cooling applications.

Magnetocaloric effect in superparamagnets

Journal of Magnetism and Magnetic Materials, 1992
The magnetocaloric effect is calculated for superparamagnetic materials as a function of temperature, field and cluster size. Assuming classical behavior, a universal curve is calculated from which an optimum cluster moment may be found for maximum entropy change upon application of a given field H at a given temperature T. Quantum effects are shown to

Magnetocaloric effect in manganites

Journal of Experimental and Theoretical Physics, 2012
The magnetocaloric effect (MCE) in La1 − xSrxMnO3, Sm0.55Sr0.45MnO3, and PrBaMn2O6 compounds is studied. The maximum values of MCE (ΔTmax) determined by a direct method in the second and third compositions and in La0.9Sr0.1MnO3 are found to be much lower than those calculated from the change of the magnetic part of entropy in the Curie temperature (TC)
