Temperature-dependent hall effect of κ-(BEDT-TTF)2Cu[N(CN)2]Cl under pressure

Abstract The electronic structure of the organic superconductor has been probed by the magnetotransport measurements. We show the first Hall effect of the salt. The Hall coefficient R H exhibited large variation with temperature, which is unusual for ordinary metals. Similarity between Hall effect data for κ-(BEDT-TTF) 2 Cu[N(CN) 2 ]Cl and other non-conventional metals is discussed.
