متن کاملDetermination of the phase diagram of the electron-doped superconductor Ba(Fe1−xCox)2As2
Systematic measurements of the resistivity, heat capacity, susceptibility, and Hall coefficient are presented for single-crystal samples of the electron-doped superconductor Ba Fe1−xCox 2As2. These data delineate an x-T phase diagram in which the single magnetic/structural phase transition that is observed for undoped BaFe2As2 at 134 K appears to split into two distinct phase transitions, both ...
متن کاملJump in specific heat at the superconducting transition temperature in Ba(Fe1â‹TMxCox)2As2 and Ba(Fe1â‹TMxNix)2As2 single crystals
We present detailed heat capacity measurements for Ba(Fe1−xCox)2As2 and Ba(Fe1−xNix)2As2 single crystals in the vicinity of the superconducting transitions. The specific-heat jump at the superconducting transition temperature (Tc), ΔCp/Tc, changes by a factor of ∼10 across these series. The ΔCp/Tc vs Tc data of this work [together with the literature data for Ba(Fe0.939Co0.061)2As2, (Ba0.55K0.4...
متن کاملSystematics of the temperature - dependent interplane resistivity in Ba ( Fe 1 − x Mx ) 2 As 2 ( M = Co , Rh , Ni , and Pd )
Temperature-dependent interplane resistivity ρc(T ) was measured systematically as a function of transitionmetal substitution in the iron-arsenide superconductors Ba(Fe1−xMx)2As2, M = Ni, Pd, Rh. The data are compared with the behavior found in Ba(Fe1−xCox)2As2, revealing resistive signatures of pseudogap. In all compounds we find resistivity crossover at a characteristic pseudogap temperature ...
متن کاملIntrinsic pinning on structural domains in underdoped single crystals of Ba(Fe1−xCox)2As2
Critical current density was studied in single crystals of Ba Fe1−xCox 2As2 for the values of x spanning the entire doping phase diagram. A noticeable enhancement was found for slightly underdoped crystals with the peak at x=0.058. Using a combination of polarized-light imaging, x-ray diffraction and magnetic measurements we associate this behavior with the intrinsic pinning on structural domai...
