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 of Gd12Co7

Solid State Communications, 2008
Abstract The sample of Gd12Co7 prepared by arc-melting and annealed for 60 days at 873 K was investigated by X-ray diffraction (X-ray), scanning electron microscope (SEM) and energy disperse spectroscopy (EDS). The result shows that the sample of Gd12Co7 in our work is almost single phase with the Ho12Co7-type monoclinic structure. The Magnetocaloric

Magnetocaloric effect in Er6Ni2Sn

Czechoslovak Journal of Physics, 2002
Anomalies observed in the specific heat and magnetization of Er6Ni2Sn indicate magnetic phase transitions at 35, 17 and 7 K connected with various types of antiferromagnetic ordering below TN (=35). We report on specific-heat measurements of polycrystalline material in magnetic fields 0–14 T in the temperature range 3.5–150 K.

Magnetocaloric effect in GdRu2Ge2

Journal of Applied Physics, 2002
We have studied the magnetocaloric effect (MCE) in GdRu2Ge2 by means of measurements of temperature and field dependence of the specific heat and the magnetization. Two anomalies were observed at T1=29 K and T2=32 K in the zero-field specific-heat curve.

Thermodynamics of the magnetocaloric effect

Physical Review B, 2001
The relationship between the behavior of the temperature-dependent heat capacity at constant pressure measured in different magnetic fields and the magnetocaloric effect in magnetic systems with and without discontinuous change of entropy is discussed.

Magnetocaloric effect in thulium

Cryogenics, 1989
Abstract Measurements of the magnetocaloric effect and the field-dependent heat capacity of thulium are reported. The magnetocaloric effect is too small to be useful for magnetic refrigeration applications except for a narrow region around the 56 K Neel point.

Simple enhancement of the magnetocaloric effect in giant magnetocaloric materials

Applied Physics Letters, 2003
A simple method of enhancing the magnetocaloric effect (MCE)) in ferromagnetic materials is described. Thin layers of pure Fe of 0.1- and 0.2-μm thickness were evaporated onto both sides of polished 0.6-mm, slices of the giant magnetocaloric material Gd5Si1.5Ge2.5.

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 Tb3Ni

AIP Conference Proceedings, 2020
The magnetocaloric effect (MCE) of Tb3Ni is discussed in this paper which is measured using dc magnetization measurements as well as specific heat measurements under magnetic field. It is found that maximum value of change in magnetic entropy was (-ΔSM) ∼6.9 J/kg-K around 60 K for a change in magnetic field of 9 T.
