초록
We have investigated the nature of charge-disproportionate spin states in mixed-phase vanadium-oxide nanosheets by using superconductive quantum interference device and electron spin resonance (ESR) measurements. The temperature dependencies of the ESR parameters corresponding to three distinct spin species manifested a ferromagnetic transition at 300 K and an electron delocalization at 350 K with an activation energy of 0.39 eV.
