Abstract

Room-temperature ferromagnetism, concurrent with antiferromagnetic order, was observed in dodecylamine-intercalated vanadium oxide nanosheets by the magnetization and electron spin resonance measurements. Charge disproportionation arising from charge localization around TP = 375 K appears to be associated with the ferromagnetic order. The ferromagnetic and the antiferromagnetic spins are found to be exchange-decoupled.
