Takada and Goto have
started with the study of exchange and correlation effects in a quasi-two-dimensional
electron system in strong magnetic fields with an immediate application
to graphite [1].
Takada has treated the problem in the framework of the local-field
correction by extending the STLS
theory which is known to be very successful
in the electron gas without a magnetic field. By considering the relation
to the fractional quantum Hall effect,
Takada is now trying to obtain a unified view of the correlation effect
with the change of dimensionality from three to two.
Takahashi and Takada have shown that the SDW formation is a more plausible candidate than CDW for the explanation of the anomaly in the magnetoresistance observed in graphite in magnetic fields of 25-50 T [2]. |
