Multiferroicity of carbon-based charge-transfer magnets

Adv Mater. 2015 Jan 27;27(4):734-9. doi: 10.1002/adma.201403396. Epub 2014 Nov 11.


A new type of carbon charge-transfer magnet, consisting of a fullerene acceptor and single-walled carbon nanotube donor, is demonstrated, which exhibits room temperature ferromagnetism and magnetoelectric (ME) coupling. In addition, external stimuli (electric/magnetic/elastic field) and the concentration of a nanocarbon complex enable the tunabilities of the magnetization and ME coupling due to the control of the charge transfer.
