- 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 T-p = 375 K appears to be associated with the ferromagnetic order. The ferromagnetic and the antiferromagnetic spins are found to be exchange-decoupled. (C) 2010 Elsevier B.V. All rights reserved.
