论文摘要

SRRUO3(SRO)是一种巡回的Ferromagnet,在电荷,自旋和晶格自由度之间具有很强的耦合。这种强的耦合表明,SRO的电子和磁性行为非常容易受到晶格失真的变化。在这里,我们展示了随着晶体学方向的修饰而变化的自旋相互作用和结果磁化形成如何变化。我们用(100),(110)和(111)表面取向制造了SRO外延薄膜,以系统地调节自旋相互作用和自旋尺寸。 (111)面向SRO薄膜中的自旋维度和增强的交换相互作用可显着抑制镁的形成。我们的研究全面证明了相关氧化物薄膜中镁形成和自旋相互作用的可调性。

SrRuO3 (SRO) is an itinerant ferromagnet with strong coupling between the charge, spin, and lattice degrees of freedom. This strong coupling suggests that the electronic and magnetic behaviors of SRO are highly susceptible to changes in the lattice distortion. Here we show how the spin interaction and resultant magnon formation change with the modification in the crystallographic orientation. We fabricated SRO epitaxial thin films with (100), (110), and (111) surface orientations, to systematically modulate the spin interaction and spin dimensionality. The reduced spin dimensionality and enhanced exchange interaction in the (111)-oriented SRO thin film significantly suppresses magnon formation. Our study comprehensively demonstrates the facile tunability of magnon formation and spin interaction in correlated oxide thin films.
