中文摘要：

在水锰矿建立 anisotropy 的更深的理解为为设备应用定制他们的磁性是有用的。这里，我们显示出那铁磁性的 La _0.7 Sr _0.3 MnO ₃(LSMO ) 薄电影，取向附生地在 SrTiO ₃(STO ) 上种底层，展出意外双 shifted 磁化曲线从在普通 biaxial 和突现的单轴的 anisotropies 之间的比赛发源。这突现的单轴的 anisotropy 能被在 LSMO/STO 接口在铁磁性的 LSMO 和 antiferromagnetic LSMO 死了的层之间联合的交换导致，它能被氧缺乏的度操作。

英文摘要：

Establishing a deeper understanding of the anisotropy in manganites is useful for tailoring their mag- netic properties for device applications. Here we showed that ferromagnetic La0.7Sr0.3MnO3 （LSMO） thin films, epitaxially grown on SrTiO3 （STO） substrates, exhibited unexpected double-shifted magnetization curves originat- ing from the competition between common biaxial and emergent uniaxial anisotropies. This emergent uniaxial anisotropy could be induced by exchange coupling between the ferromagnetic LSMO and an antiferromag- netic LSMO dead layer at the LSMO/STO interface, which could be manipulated by the degree of oxygen deficiency.
