Muon spin rotation and infrared spectroscopy study of magnetism and superconductivity in Ba1−xKxFe2As2
2017
Physical review B
Using muon spin rotation and infrared spectroscopy we study the relation between magnetism and superconductivity in Ba _1-x K _x Fe _2 As _2 single crystals from the underdoped to the slightly overdoped regime. We find that the Fe magnetic moment is only moderately suppressed in most of the underdoped region where it decreases more slowly than the Néel-temperature, T^N . This applies for both the total Fe moment obtained from muon spin rotation and for the itinerant component that is deduced
