摘要:

我们报告的一些结构相同,但化学上不同的过渡金属氧化物的系统研究,以确定如何材料的特定属性,如组合物和应变影响异质结构的界面处的属性。我们的研究考虑了一系列的结构,包含两层铁磁SrRuO3,与反铁磁绝缘锰氧化物夹在中间。结果表明,如何控制界面铁磁性的强度和相对取向的关联电子材料的方法,通过价态变化和衬底诱导的应变,分别。

英文摘要:

We report on a systematic study of a number of structurally identical but chemically distinct transition metal oxides in order to determine how the material-specific properties such as the composition and the strain affect the properties at the interface of heterostructures. Our study considers a series of structures containing two layers of ferromagnetic SrRuO3, with antiferromagnetic insulating manganites sandwiched in between. The results demonstrate how to control the strength and relative orientation of interfacial ferromagnetism in correlated electron materials by means of valence state variation and substrate-induced strain, respectively.
