Abstract

Zero field (ZF) muon spin relaxation measurements on the organic metal κ-BETS2FeCl4 clearly show the formation of an antiferromagnetically ordered state below TN = 0.45 K. The magnetic order remains unperturbed on cooling through the superconducting transition Tc ∼0.17 K, providing unambiguous evidence for the coexistence of antiferromagnetic order and superconductivity in this system. Detailed studies of the internal field distribution show contrasting behavior for different muon sites and provide experimental evidence for an ordered spin structure in the BETS layers in addition to that taking place in the Fe layers.
