X-ray diffraction and atomic-force microscopy show that all NiO layers are single-phase, face-centered pseudo-cubic, atomically smooth, root-main-square (RMS) surface roughness <0.15 nm, and form abrupt interfaces with LSMO. High-resolution reciprocal-space maps reveal that the films are largely relaxed, but exhibit a slight compressive distortion, yielding unit-cell volumes larger than bulk NiO. Despite a nominal ≈7% lattice mismatch, aberration-corrected scanning transmission electron microscopy uncovers an array of misfit dislocations at the NiO/LSMO interface that help to accommodate strain allowing epitaxial growth of NiO layers. On (001)-oriented samples, the four antiferromagnetic T-domains are oblique to the sample plane, while on the (111) case, one lies in-plane. This in-plane domain shows greater spacing between ferromagnetic (111) planes due to unit cell distortion. This structural domain splitting can influence magnetic order and spin transmission efficiency, highlighting crystallographic orientation as a key factor in designing high-performance spintronic devices.This work has received funding from the State Investigation Agency, through the Severo Ochoa Programme for Centres of Excellence in R&D (CEX2023–001263-S and CEX2023-001286-S) and “OXISOT” (PID2021-128410OB-I00), “AMONANO” (PID2020-112914RB-I00), and HTSUPERFUN (PID2021-124680OB-I00) funded by MCIN/AEI/ 10.13039/ 501100011033, from the Gobierno de Aragon project E13_23R, including FEDER funding, and by “ERDF A way of making Europe,” by the “European Union.” Shoulong Chen acknowledges financial support from the China Scholarship Council (CSC).
