- Abstract
The article focuses on research into the development of magnetic refrigeration. It states that the magnetocaloric effect, a thermodynamically reversible phenomena, can be used for heat pumping. It mentions that this effect is observed in a small range of magnetic materials when they are close to their Curie temperature point. It states that electron spins within a magnetocaloric material are forced into alignment with strong magnetic fields and go into a higher-ordered, lower energy state resulting in a temperature increase. It also states that when the magnetic field is lowered the process is reversed and the material's temperature drops. It mentions that research is going into enhancing the performance of systems using magnetocaloric materials and permanent magnetic materials available.
