Magnetocaloric Effect in RСo2 Compounds

Article Preview

Abstract:

The direct measurements of the magnetocaloric effect (MCE) and the magnetization have been conducted for a large number of compounds based on RCo2 (R = Tb, Ho) with substitutions by nonmagnetic elements (Y, Al, Ga) in rare earth and 3d- sublattices. The concentration dependencies of the Curie temperature and the value of MCE are discussed. The linear dependencies of the value of the MCE from the second power of the magnetization were find out at the region of the phase transition of the second type .
