Pressure effects on the electron-doped high Tc superconductor BaFe2−xCoxAs2
Abstract
Application of pressure or electron doping through Co substitution into Fe sites transforms the itinerant antiferromagnet BaFe2As2 into a superconductor with Tc exceeding 20 K. We carried out systematic transport measurements of BaFe2−xCoxAs2 superconductors in pressures up to 2.5 GPa, and elucidated the interplay between the effects of electron doping and pressure. For the underdoped sample with nominal composition x = 0.08, application of …
