SrRuO₃ is known to exhibit strong magnetocrystalline effect, which enables us to control its magnetic properties using lattice engineering. The magnetocrystalline effect of SrRuO₃ is systematically investigated under both compressive and tensile strain by depositing SrRuO₃ thin films on various oxide substrates with different in‐plane lattice mismatch. All SrRuO₃ films have high crystallinity with flat interface and surface. It is found that out‐of‐plane lattice constant is decreased with increasing strain. Moreover, unit cell volume decreases with strain due to structural distortion attributable to RuO₆ octahedral distortion as theoretically expected. However, magnetization does not match to any of the theoretical models only considering structural changes; at current stage, internal interactions rather than structural changes seem critical in determining the magnetization of the SrRuO₃ films. This study can play a crucial role in understanding internal correlations of magnetic properties in ruthenate films and can trigger research on magnetic functionality.

基底引起的应变对SrRuO3薄膜磁性能的影响可忽略不计

已知SrRuO ₃表现出很强的磁晶效应，这使我们能够使用晶格工程技术控制其磁性能。通过在不同面内晶格失配的各种氧化物基底上沉积SrRuO ₃薄膜，系统地研究了SrRuO ₃在压缩和拉伸应变下的磁晶效应。所有SrRuO ₃薄膜都具有高结晶度，界面和表面平坦。发现面外晶格常数随应变增加而降低。而且，由于归因于RuO _6的结构变形，晶胞体积随着应变而减小。八面体变形，如理论上预期的那样。但是，仅考虑结构变化，磁化强度与任何理论模型都不匹配。在当前阶段，内部相互作用而不是结构变化似乎对于确定SrRuO ₃薄膜的磁化强度至关重要。这项研究在理解钌酸盐薄膜的磁性内部相关性方面可以发挥关键作用，并可以引发对磁性功能的研究。
