Fig. 4: TEM and DFT results of the interface.
From: Real-space observation of ferroelectrically induced magnetic spin crystal in SrRuO3
a Dark and bright field TEM images of the SRO–PTO interface with fitted atomic model overlayed. Scale bar is 1 nm. b Atomic displacements for the oxygen—A site shift (blue), the B site—A site shift (orange) and the B site to octahedral cage (green) acquired from the ABF images. c DFT simulated of the same atomic displacements around the SRO–PTO interface.
