About this course

The course “Application of magnetic materials” covers the whole range of topics concerning magnetocaloric phenomena, related materials and prototype devices. Magnetocaloric effect is at the peak of interest of modern material physics as it provides the mechanism of magnetic cooling based on the temperature change of magnetic media, guided by the means of external magnetic field. Magnetic cooling based devices may replace environmentally unfriendly freon fridges so the area of their development attracts high support both from fundamental science and industry.

The course starts with the description of theoretical approach which describes the magnetocaloric effect from thermodynamical point of view. The second part is devoted to description of thermodynamic cycles and practical aspects of their application. Then materials for magnetocaloric applications, both low- and near-room-temperature, are complexly investigated. Clues for how to look for materials, where high values of magnetocaloric effect may be observed, are given. Several approaches for searching the material possessed tricritical point were described. The routine how to deal with hysteresis in the material with the first order of phase transition was considered. In the end of the course the state of art in MCE-based devices is exposed and predictions of the nearest future of the area are stated.

The purpose of the course “Application of magnetic materials” is to study theoretical background and experimental approaches of the magnetic refrigeration systems based on the magnetocaloric effect (MCE). Features of magnetocaloric materials, techniques of MCE measurements and applicable prototypes will be learned.

The course addresses both theory and experiment that are vital for gaining an essential understanding of fundamental science and state-of-the-art applications of magnetocaloric materials.

Dr. Dmitriy Yu. Karpenkov, National University of Science and Technology MISiS
