| Outline of Final Research Achievements |
Magnetic refrigeration method makes use of the magnetocaloric effect (MCE) where some magnetic materials exhaust or absorb heat by applying or removing external magnetic fields. MCE is induced by the internal magnetic entropy change of magnetic material, thus magnetic refrigeration can operate an ideal cycle like Carnot.
In this research, we investigated new magnetic materials that will be useful for hydrogen magnetic refrigeration. It is possible to control temperature and magnetic field dependence of the MCE using magnetic materials with multiple transitions. Magnetic materials of intermetallic compounds such as (ErDy)NiAl, (Er,Dy)Al2, Er(Co,Ni)2, Er(Co,Cu)2 were synthesized. Magnetic and thermal properties of those compounds were measured in order to evaluated MCE. MCE results for oxides, sulfide that have rare-earth elements were also studied as useful materials
