Title: Anomalous low-temperature and high-field magnetoresistance in the organic superconductor [beta][sup [double prime]]-(BEDT-TTF)[sub 2]SF[sub 5]CH[sub 2]CF[sub 2]SO[sub 3]

Abstract

We report direct observations of anomalous magnetic-field and temperature dependences of the Shubnikov[endash]de Haas oscillations in the organic superconductor [beta][sup [double prime]]-(BEDT-TTF)[sub 2]SF[sub 5]CH[sub 2]CF[sub 2]SO[sub 3]. Unlike other BEDT-TTF based organic superconductors, a nonmetallic temperature dependence of the background magnetoresistance is clearly observed. It is speculated that the nonmetallic behavior may arise from a partial nesting of the open orbits, similar to the field-induced density wave in the quasi-one-dimensional systems or a charge localization. The analysis of the magnetoresistance oscillations are found to deviate from the conventional Lifshitz-Kosevich description at high field and low temperatures.
