英文摘要	Moire engineering has rapidly gained currency as a means to manipulate electronic states of matter in van der Waals heterostructures. Now, the feat is achieved in epitaxially grown oxide heterostructures, thus opening up fresh opportunities for strongly correlated electronic systems. Moire engineering has recently emerged as an effective approach to control quantum phenomena in condensed matter systems(1-6). In van der Waals heterostructures, moire patterns can be formed by lattice misorientation between adjacent atomic layers, creating long-range electronic order. Moire engineering has so far been executed solely in stacked van der Waals multilayers. Here we describe electronic moire patterns in films of a prototypical magnetoresistive oxide, La0.67Sr0.33MnO3, epitaxially grown on LaAlO3 substrates. Using scanning probe nanoimaging, we observe microscopic moire profiles attributed to the coexistence and interaction of two distinct incommensurate patterns of strain modulation within these films. The net effect is that both the electronic conductivity and ferromagnetism of La0.67Sr0.33MnO3 are modulated by periodic moire textures extending over mesoscopic scales. Our work provides a potential route to achieving spatially patterned electronic textures on demand in strained epitaxial materials.
