The angular dependent magnetoresistance oscillation (ADMRO) effect in at-(BEDT-TTF)2-MHg(SCN)4 I-M: K, NH4] has been studied by two-axis rotation of the crystals in magnetic field. While the ADMRO in NH4Hg-salt is of the standard type arising from a warped cylindrical Fermi surface, that in KHg-salt

We report magnetoresistance measurements on ET, KHg(SCN), and /3"ET2 AuBr,. Both show Shubnikov-de Haas oscillation frequencies additional to those expected from band structure calculations, and other magnetoresistance anomalies occur (e.g. hysteresis, "kink" structures). These effects are explained
Shubnikov~te Haas (SdH) measurements in the quasi-two-dimensional (2D) organic conductor (BEDT-TTF)2T1Hg(SCN)4 have been carried out to investigate the ground state. The closed orbit of the 2D Fermi surface and the magnetic breakdown orbit are observed above 10 T. Below 3 T, three small closed orbit
