Se77 NMR investigation of the KxFe2-ySe2 high-Tc superconductor (Tc=33 K)
Abstract
We report comprehensive Se77 NMR measurements on a single crystalline sample of the recently discovered FeSe-based high-temperature superconductor KxFe2-ySe2 (Tc=33 K) in a broad temperature range up to 290 K. Despite deviations from the stoichiometric KFe2Se2 composition, we observed Se77 NMR line shapes as narrow as 4.5 kHz under a magnetic field applied along the crystal c axis, and found no evidence for co-existence of magnetic order with …
