摘要

Under this grant, researcher has conducted detailed studies of magnetocaloric nanomaterials for solid state cooling applications. Such materials are of great current interest in solid state cooling. Present work on synthesis, characterization and property evaluation of magnetocaloric materials is summarized. Magnetic refrigeration systems offer good potential to reduce (1) global energy consumption and (2) use of ozone-depleting compounds, greenhouse gases and hazardous chemicals. The experimental investigation of magnetocaloric effects and structural properties of Fe80-xGdxCr8B12 (x = 0, 5, 8, 15) alloys has therefore been studied. Fe80Cr8B12 alloys exhibit good magnetocaloric properties near room temperature. Gd, which is well-known to exhibit good magnetocaloric effects in room temperature, was alloyed in Fe-Cr-B base alloys. The increase of Gd additions displaces the Curie temperature of the alloy to higher temperatures without significant depreciation of entropy change. It is also shown that a phenomenological model which describes the magnetic entropy change is applicable to these alloys.
