oommf中的交换常数单位
|
| 这是一个文章的审稿意见The authors write:"The exchange energy constant between the hard and soft layers is set as Ahs =10^−11 J/m." This statement is misleading. The exchange constant in units of J/m is a bulk property. There are only two possibilities (1) Either there is a phase that separates the Nd2Fe14B and Fe. This intermediate phase will have a certain thickness. In addition to the exchange constant the authors should give the thickness of the intermediate phase. (2) There is a coupling between the different phases. This is normally expressed as a surface energy. The proper units will be J/(m*m).我看到很多文献中所用到的软硬磁层之间的交换常数的单位都是J/m，可是审稿人提到的这个intermediate phase 的厚度又怎么得知呢？还是不需要考虑吗？求各位牛人帮帮我，非常感谢！ |
