| Outline of Final Research Achievements |
In order to achieve a high efficient magnetic refrigeration cycle for hydrogen liquefaction, we considered a new cycle consisting of cascade connected two AMR beds. This is called as a double acting AMR. This configuration will operate on the AMR cycle with more stable and efficient. We developed a calculation code to estimate thermal and magnetic properties with more accuracy by using Monte Carlo method. This provided the better fitting especially in the non-linear properties. Then, we developed a cycle simulation code including Monte Carlo method and it showed good predictions for the experiments. Based on the simulation, we constructed the experimental machine at room temperatures, because of easier thermal condition. The new AMR cycle showed very positive results with higher efficiency. This result will be able to apply even in the low temperatures such as hydrogen region.
