Fig. 1 — a Temperature and b magnetic field-dependent magnetization of LCO thin films with different thicknesses measured by applying a magnetic field along the IP direction. The inset of (a) shows the thickness-dependent FM T_C. Temperature-dependent magnetization curves were measured during LCO thin films warming after a field cooling of 1 kOe. c Z-contrast HAADF-STEM image of LCO 25 uc in cross-sectional orientation, projected along the [010] zone axis. d–h Atomically resolved STEM-EELS elemental maps of Sr, Ti, La, and Co, and a colored RGB overlay, respectively. Scale bar: 1 nm. i EELS signal intensity profiles across the LCO/STO interface extracted along the white arrow direction in (h).
