Interactions, disorder and local defects in graphite
arXiv:cond-mat/0409567 · doi:10.1016/j.jpcs.2005.10.134
Abstract
Recent experiments report the existence of ferromagnetic and superconducting fluctuations in graphite at unexpectedly high temperatures. The interplay of disorder and interactions in a 2D graphene layer is shown to give rise to a rich phase diagram where strong coupling phases can become stable. Local defects can explain the ferromagnetic signals.
