We also demonstrate that oxygen octahedral deformation cannot explain the trend in PMA. These results reveal a new degree of freedom to control PMA, enabling discovery of emergent magnetic textures and …
Quantifying octahedral rotations in strained perovskite oxide films
WebJan 18, 2024 · Public Summary. We review and summarize the structure of perovskite oxides, the characterization methods of oxygen octahedral rotation, as well as the response for transport, electrical polarization, and magnetism. Half-order X-ray diffraction and STEM (HAADF and ABF) are two most common techniques to characterize the octahendral … WebAug 1, 2024 · Here we demonstrate a conceptually new type of interface induced PMA that is controlled by oxygen octahedral rotation. In superlattices comprised of La1-xSrxMnO3 and SrIrO3, we find that all superlattices (0<=x<=1) exhibit ferromagnetism despite the fact that La1-xSrxMnO3 is antiferromagnetic for x>0.5. ed schultz wasatch peaks
