| Abstract(J) | 多くの磁気冷凍研究では，大きな磁気エントロピー変化を得るために超伝導電磁石による強磁場が必須である．本稿では，希土類Hoを用いた弱磁場変化による高効率な磁気冷凍法を提案する．この方法は，永久磁石で発生可能な磁場によって動作するため，低コストでコンパクトな液体水素貯蔵・運搬に応用できる可能性がある． Translation |
| Abstract(E) | Magnetic refrigeration (MR) is a method of cooling matter using a magnetic field. Most research to date has employed high magnetic fields (at least 5 T) to obtain a large entropy change, which requires a superconducting magnet and, therefore, incurs a large energy cost. Here we propose an alternative highly efficient cooling technique in which small magnetic field changes 0.4 T can obtain a cooling efficiency. Our MR system with holmium can be implemented using permanent magnets, providing a possibility to be used for low-cost and compact hydrogen-storage and carrier applications. |
