Abstract

The Shubnikov-de Haas (SdH) and magnetoresistance measurements have been performed in an organic metal β″-(BEDT-TFF)2AuBr2. Absence of saturation in the magnetoresistance up to 13 T suggests that this salt is a compensated metal. The SdH oscillations are consistently understood by assuming that three cylindrical Fermi surfaces are present. The frequencies of the SdH oscillations corresponding to the Fermi surfaces are determined to be 41.5 T, 139 T, and 181 T for H//b*-axis. An anomalous maximum in the resistance is found at about 9.5 K for H//b*-axis although no anomaly is observed for H//plane.
