Inducing ferromagnetism in pure vanadium oxide by precisely adjusting the oxidation state of its ions

"transition metal-insulator vanadium oxide changes its electrical conductivity depending on temperature... without applying doping/ introducing structural defects, is antiferromagnetic/ paramagnetic, limiting application as magnet... deposited thin layers of metallic vanadium, systematically adjusted oxygen concentration producing thin films with differing oxidation levels... lower oxidation (Vanadium III/ IV coexisting) leads to stronger ferromagnetism/ vice-versa... emerged in localized regions... data storage"
