Magnetocaloric Effect in Perovskite Manganites: 81 (Materials Research Foundations)

For environmental concerns it is highly desirable to replace gas-based refrigeration by magnetic refrigeration. Magnetic refrigeration has significant advantages such as small volume chemical stability low cost non-toxicity and not causing sound pollution. Among the pertinent magnetocaloric materials perovskite manganites are of special interest because they exhibit extremely large magnetic entropy and adiabatic temperature variations a small thermal or magnetic hysteresis high chemical stability. Further the Curie temperature and saturation magnetization can be tailored by changing doping element and doping concentrations.
