Abstract

Physical quantities affecting the magnitude of magnetocaloric effect in ferro- and ferrimagnetic materials with first and second order magnetic phase transitions are considered. Governing equations for the main characteristics of the magnetocaloric effect are given and analyzed. Their outcomes are compared with the experimental results.
