Field-induced anomaly in the magnetoresistance of (EDO-TTFVO)(2)FeCl4 below 1.5 K

摘要

The magnetoresistance (MR) for a new organic conductor, beta"-(EDO-TTFVO)(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 pi-electrons on the EDO-TTFVO donors and the d-spins on the magnetic FeCl4- ions.
