我们利用反射几何中偏振中子和软x射线束的独特空间灵敏度来测量铁磁体和反铁磁体之间界面磁化的深度依赖关系。界面附近的净无补偿磁化响应于外加磁场，而反铁磁体中的无补偿自旋被钉住，从而提供了建立交换偏置的手段。
We have used the unique spatial sensitivity of polarized neutron and soft x-ray beams in reflection geometry to measure the depth dependence of magnetization across the interface between a ferromagnet and an antiferromagnet. The net uncompensated magnetization near the interface responds to applied field, while uncompensated spins in the antiferromagnet bulk are pinned, thus providing a means to establish exchange bias.
