Zero-Field muSR Search for a Time-Reversal-Symmetry-Breaking Mixed Pairing State in Superconducting Ba1-xKxFe2As2

Z. Lotfi Mahyari, A. Cannell, C. Gomez +6

We report the results of a zero-field muon spin relaxation (ZF-muSR) study of superconducting Ba1-xKxFe2As2 (0.5 < x < 0.9) in search of weak spontaneous internal magnetic fields a…
