Abstract

Muon-spin-relaxation (μSR) measurements in the transverse-field (TF) of 30 G were carried out from 7 K down to 1.8 K on the non-magnetic anion-based organic superconductor λ-(BETS)2GaCl4. The TF-μSR time spectrum showed a significant increase with the Gaussian-type damping behavior below the superconducting transition temperature TC = 5 K confirming the bulk SC state with the full volume fraction. The zero-field (ZF) μSR time spectrum did not show any change against the temperature down to 1.7 K, suggesting that the time reversal symmetry of the Cooper pair might not be broken.
