Magnetocaloric Effect in La 1−x Cd x MnO 3
TLDR
In this article, the magnetocaloric effect of the LSCM system was investigated for the Ericson-cycle magnetic refrigerator and it was shown that the magnetic entropy change distribution of the lSCM is much more uniform than that of gadolinium.Abstract:
Calculations of the magnetocaloric effect for La1−x

MnO3 (LSCM) upon 0.05 T magnetic field variation have been carried out. 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. Furthermore, at different concentrations of Cd, the temperature range between 150 K and room temperature can be covered using the La1−x

MnO3 system. Therefore, the LSCM system is beneficial for manipulating magnetocaloric refrigeration that occurs in various temperatures.read more

Interaction between the d -Shells in the Transition Metals. II. Ferromagnetic Compounds of Manganese with Perovskite Structure
TL;DR: In this paper, it was shown that both electrical conduction and ferromagnetic coupling in these compounds arise from a double exchange process, and a quantitative relation was developed between electrical conductivity and the Ferromagnetic Curie temperature.

Effects of Double Exchange in Magnetic Crystals
TL;DR: In this article, it was shown that mobile electrons always give rise to a distortion of the ground state spin arrangement, since electron transfer lowers the energy by a term of first order in the distortion angles.
