Dual origin of defect magnetism in graphene and its reversible switching by molecular doping
R. R. Nair, I-Ling Tsai, M. Sepioni +7
A possibility to control magnetic properties by using electric fields is one of the most desirable characteristics for spintronics applications. Finding a suitable material remains…
Reply to Comment by D. Spemann et al [EPL 98 (2012) 57006, arXiv:1204.2992]
M. Sepioni, R. R. Nair, I. -Ling Tsai +2
This article is a reply to the Comment by D. Spemann et al (arXiv:1204.2992) in response to our paper 'Revealing common artifacts due to ferromagnetic inclusions in highly oriented…
Revealing common artifacts due to ferromagnetic inclusions in highly-oriented pyrolytic graphite
M. Sepioni, R. R. Nair, I-Ling Tsai +2
We report on an extensive investigation to figure out the origin of room-temperature ferromagnetism that is commonly observed by SQUID magnetometry in highly-oriented pyrolytic gra…
Spin-half paramagnetism in graphene induced by point defects
R. R. Nair, M. Sepioni, I-Ling Tsai +6
Using magnetization measurements, we show that point defects in graphene - fluorine adatoms and irradiation defects (vacancies) - carry magnetic moments with spin 1/2. Both types o…
Limits on intrinsic magnetism in graphene
M. Sepioni, R. R. Nair, S. Rablen +5
We have studied magnetization of graphene nanocrystals obtained by sonic exfoliation of graphite. No ferromagnetism is detected at any temperature down to 2 K. Neither do we find s…
