The calculated local spin results are comparable to previous ones and the obtained pariwise exchange coupling constants are in well agreement with experiments.
通过计算得到的局域自旋结果和前人的具有可比性，同时所得的磁交换耦合常数和实验值很吻合。

The electromagnetic attraction is pictured as being caused by the exchange of large Numbers of virtual massless particles of spin 1, called photons.
The invention belongs to the technical field of magnetic materials and devices and relates to a magnetic recording technology, in particular to an exchange bias field-type spin valve.
