DESCRIPTION:Speaker: Marta Gibert\nhosted by Kimberly Modic\nAbstract: Atom
 ically engineered transition-metal-oxide heterostructures provide a powerf
 ul platform to stabilize metastable phases and generate emergent propertie
 s by stacking dissimilar materials with atomic-scale precision. In this ta
 lk\, we present two representative examples. First\, we address the long-d
 ebated properties of SrCrO thin films. Through the growth of high-quality\
 , strained films via magnetron sputtering\, we demonstrate that SrCrO's gr
 ound state is that of a metallic antiferromagnet. A combination of muon sp
 in relaxation\, SQUID magnetometry\, XMCD\, and XMLD reveals an antiferrom
 agnetic transition at a Néel temperature of approximately 150 K — about
  100 K higher than in the bulk. Additionally\, increasing tensile strain i
 nduces a metal-insulator transition in these films while leaving the magne
 tic transition unaffected. Second\, we investigate structure–property re
 lationships in ferromagnetic double-perovskite LaNiMnO thin films as their
  thickness is reduced to a few unit cells [1]. Using atomically controlled
  LaNiMnO/RENiMnO (RE = Nd\, Sm) superlattices\, we probe the length scale 
 of interfacial coupling between ferromagnetic and paramagnetic layers and 
 show that the magnetic transition temperature can be tuned via superlattic
 e periodicity [2]. Finally\, we demonstrate that these superlattices enabl
 e the rational design of antipolar distortions\, paving the way for multif
 erroicity in artificially layered oxide systems [3]. [1] G. De Luca et al.
