Abstract
Magnetoresistance anisotropy of (BEDT-TTF)2TlHg(XCN)4 with X = S and S e has been studied in magnetic fields up to 30 T. The magnetoresistanc e of the Se-containing salt is shown to be dominated by an extremely w eakly warped Fermi surface cylinder. The behavior of the compound with X = S is more complicated. At fields below 20 T the magnetoresistance oscillations reveal a commensurate superstructure associated most lik ely with the antiferromagnetic phase transition. Higher fields, above 27 T, appear to suppress the magnetic order and restore the high-tempe rature electronic state.
