Magnetocaloric effect in La1.25Sr0.75MnCoO6

Journal of Thermal Analysis and Calorimetry, 2013
The magnetocaloric properties of La1.25Sr0.75MnCoO6 (LSCM) manganites that were synthesized at 750 and 1,300 °C have been investigated. It is found that magnetic entropy change distribution of the LSCM is much more uniform than that of gadolinium. This feature is desirable for an Ericson-cycle magnetic refrigerator.

Magnetocaloric effect in ferrite nanoparticles

Journal of Magnetism and Magnetic Materials, 2006
Abstract A comparative study of the magnetocaloric effect (MCE) is reported in two different types of chemically synthesized magnetic nanoparticle systems—cobalt ferrite and manganese zinc ferrite with mean size around 5 and 15 nm, respectively.

Magnetocaloric Effect in ErSi Compound

IEEE Transactions on Magnetics, 2011
The magnetic properties and magnetocaloric effects (MCEs) have been investigated in ErSi compound, which crystallizes in the orthorhombic CrB-type structure. This compound is antiferromagnetic (AFM) with a Neel temperature TN of 12.5 K. The measurements of the temperature and field dependences of the magnetization clearly show that the ErSi compound ...

Who discovered the magnetocaloric effect?

The European Physical Journal H, 2013
A magnetic body changes its thermal state when subjected to a changing magnetic field. In particular, if done under adiabatic conditions, its temperature changes. For the past 15 years the magnetocaloric effect has been the focus of significant research due to its possible application for efficient refrigeration near room temperature. At the same time,

Magnetocaloric effect in HoMnO3 crystal

Applied Physics Letters, 2010
We have investigated the magnetic and magnetocaloric properties of HoMnO3 single crystal. HoMnO3 displays a series of complicated phase transitions due to the long range ordering of Mn3+ and Ho3+ moments. Field variation in magnetization generates a metamagnetic transition and produces an entropy change of 13.1 J/kg K at 7 T in the vicinity of ...

Magnetocaloric effect in hexagonal Yb0.9Mg0.1MnO3

Materials Letters, 2015
Abstract Polycrystalline hexagonal Yb0.9Mg0.1MnO3 is examined for its magnetic, and magnetocaloric properties. Antiferromagnetic ordering of the Mn sublattice occurs at TN=88 K. At low temperature (~3.5 K), the compound shows ferromagnetic (FM) ordering attributed to Yb in site 2a.

Great Magnetocaloric Effect of La0.27Nd0.4Ca0.33MnO3

Journal of Superconductivity and Novel Magnetism, 2015
A magnetocaloric effect has been investigated in the La0.27Nd0.4Ca0.33MnO3. The results show that the maximum magnetic entropy change of La0.27Nd0.4Ca0.33MnO3 in the magnetic field change of 5.0 T is 10.05 J. kg−1. K−1 at 135 K, which is nearly equal Gd in the same magnetic field change.
