High quality epitaxial SrCoO x (oxygen deficient SrCoO 3 ) thin films were grown on (110) DyScO3 substrates by pulsed laser deposition.The disappearance of half order peaks in X‐ray diffraction as well as the XAS at the O K‐edge indicates an oxygen content of x ≈ 2.8 in the thin films. Magnetization measurements reveal that the specific substrate strain suppresses the ferromagnetism found in the corresponding bulk material and the emergence of an antiferromagnetic‐type spin correlation as predicted by theoretical calculations. Our work demonstrates that the magnetism can be tuned by in‐plane strain in SrCoO x thin films.
