Abstract

This is the study of relation between thermal and magnetic properties of permanent magnets. The concept of adiabatic demagnetization gives the basic idea on variation in temperature of paramagnetic substances due to the application of magnetic field. With the understanding of adiabatic demagnetization the variations in temperature of ferromagnetic materials can be explained. In both cases, adiabatic demagnetization tells us about conservation of energy. The study on thermal properties of ferromagnetic materials at cryogenic temperatures gives the amount of thermal energy being transferred from or to the surroundings and hence gives the variations in magnetic fields due to temperature changes. As samarium cobalt rare earth permanent magnet do quite well at cryogenic temperatures, this study is much useful in future applications of permanent magnets in space for a renewable energy source. This will enable us to look into the design and working of a device that can convert thermal energy to mechanical energy which leads to thinking of energy conversion without causing harm to our environment. Numerous research works report the successful use of samarium cobalt to temperatures as low as 2 K.
