| 1. | A study of magnetic entropy effect of alloy gdzn 合金的磁熵效应研究 |
| 2. | Magnetic properties and magnetic entropy change of ce2fe16al near curie temperature 化合物在居里温度附近的磁性和磁熵变 |
| 3. | The atom of which number of valence electron is half of the sub - layer of electron has magnetic entropy value according to the theoretic calculation 根据理论计算,价电子为半满的原子全角动量量子数j值比较大,从而有大的磁熵值。 |
| 4. | The change of magnetic entropy ( asm ) is the main parameter evaluating the quality of magnetic refrigerant materials and it can not be gotten by direct way now 衡量磁致冷材料性能好坏的主要参量是磁熵变sm ,目前无法通过直接测量得到磁熵变。 |
| 5. | Though asm of eufe is 0 . 199 j / kg ? k less than that of gdsige , it can be higher than now if more reasonable process is taken , eufe can become magnetic refrigerant materials in practice some day 二者相比, eufe的磁熵变要低0 . 199j kg ? k ,如果改进工艺,制备单相eufe合金,其磁熵变还会有所提高, eufe合金有可能成为一种实用的磁致冷材料。 |
| 6. | It is a excellent method for the whole analysis can be executed by this way . the biggest asm of eufe sample sintering by sps is 1 . 6913 / kg ? k under it magnetic field and which of melting sample gdsige is 1 . 9j / kg - k under same condition of measurement with eufe 通过机械合金化和sps烧结得到含有eufe合金的混合物,在1t磁场下测量,最大磁熵变为1 . 691j kg ? k ;同时,用悬浮炉熔炼法制备了gdsige样品,在1t磁场下,该系样品的最大磁熵变是1 . 9j kg ? k 。 |
| 7. | The magnetic ground state of lafe _ ( 11 . 4 ) al _ ( 1 . 6 ) cx compound changes from antiferromagnetic to ferromagnetic for x > 0 . 06 and the curie temperature increased monotonously with the increase of carbon content . a large magnetic entropy change was obtained near the phase transition temperature and the refrigerant capacity is good 当碳含量高于0 . 06时,化合物的基态由反铁磁变为铁磁且居里温度随c含量的增加向高温区移动,在各自相变温度附近保持较大磁熵变,具有良好的磁制冷能力。 |
