X射线显微镜使用磁性线性二向色性的零场生长的多畴Co/LaFeO 3铁磁体/反铁磁体样品显示了随机方向和幅度的局部交换偏置。个别微米尺寸的磁畴的局部偏置的统计分析表明，随着磁畴尺寸的减小，偏置场增加，这被认为是介导界面耦合的钉扎的，未补偿的自旋的随机分布所预期的。发现与畴直径的倒数呈线性关系。（C）2004美国物理研究所。
X-ray microscopy using magnetic linear dichroism of a zero-field-grown multidomain Co/LaFeO3 ferromagnet/antiferromagnet sample shows a local exchange bias of random direction and magnitude. A statistical analysis of the local bias of individual micron-size magnetic domains demonstrates an increasing bias field with decreasing domain size as expected for a random distribution of pinned, uncompensated spins, which are believed to mediate the interface coupling. A linear dependence with the inverse domain diameter is found. (C) 2004 American Institute of Physics.
