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)₂Fe_xGa_1−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.
