摘要
The magnetoresistance (MR) for a new organic conductor, β”-(EDOTTFVO)2 FeCl4 which exhibits metallic temperature dependence of the resistivity down to 0.3 K, was studied. Remarkable and unusual features were found: isotropic MR below 3 T, dip anomaly below 3 K, and SdH effect above 17 T. These features are discussed in terms of an interaction between the π-electrons on the EDO-TTFVO donors and the d-spins on the magnetic FeCl4− ions.
