We report on magnetic properties of CoxIn2Se3 layered crystals intercalated by cobalt. The electrochemical intercalation was carried out in the presence of external magnetic field and without it. In addition, morphology of the van der Waals surfaces of the crystal layers was studied as well. It was established that ferromagnetic ordering at room temperature is observed only in the crystals which were intercalated in the presence of external magnetic field. The crystals are a nanocomposite material that consists of a layered matrix and arrays of Co nanorings and nanowires formed on the van der Waals surfaces of In2Se3 layers. We investigate self-organisation of Co magnetic nanostructures on the van der Waals surfaces of layered semiconductor crystals during electrochemical intercalation in the presence of external magnetic field and magnetic properties of such structures.
