Investigation on structural, morphological and magnetic properties of Barium Cobaltite (BaCoO3) nanoparticle

•BaCoO3 is prepared by solvothermal method and systematically investigated the structural and magnetic property.•The XRD patterns revealed the hexagonal crystal structure of BaCoO3 and the scanning electron microscope reveals a layered morphology.•A detailed XPS scan, which displays mixed spin states responsible for the RT ferromagnetism, validated the octahedral dissolution of CoO6.•BaCoO3 displays a ferromagnetic order at ambient temperature, suggesting the material might be used in magnetic devices.
