Phase diagram and anomalous constant resistivity state of a magnetic organic superconducting alloy, λ-(BETS)2FexGa1−xCl4
Abstract
The combination of an organic superconductor, λ-(BETS)2GaCl4, and a field-induced organic superconductor, λ-(BETS)2FeCl4, provided unprecedented organic alloys, λ-(BETS)2FexGa1−xCl4, with the superconducting phase expanded by intruding into the adjacent antiferromagnetic insulating phase and an anomalous constant resistivity state located between the normal metallic and zero-resistivity states.
