Hole-doped BaFe2-xCrxAs2 Crystals: A Case of Non-superconductivity
We investigate the physical properties and electronic structure upon Cr-doping in the iron arsenide layers of BaFe2As2. This form of hole-doping leads to suppression of the magnetic/structural phase transition in BaFe2-xCrxAs2 for x > 0, but does not lead to superconductivity. For various x values, temperature dependence of the resistivity, specific heat, magnetic susceptibility, Hall coefficie...
متن کاملSuperconductivity induced by Ni doping in BaFe2As2 single crystals
A series of 122 phase BaFe2−xNixAs2 (x = 0, 0.055, 0.096, 0.18 and 0.23) single crystals was grown by the self-flux method and a dome-like Ni doping dependence of the superconducting transition temperature was discovered. The transition temperature T on c reaches a maximum of 20.5K at x = 0.096, and it drops to below 4K as x > 0.23. The negative thermopower in the normal state indicates that th...
متن کاملStructural and Magnetic Phase Transitions near Optimal Superconductivity in BaFe2(As(1-x)Px)2.
We use nuclear magnetic resonance (NMR), high-resolution x-ray, and neutron scattering studies to study structural and magnetic phase transitions in phosphorus-doped BaFe2(As(1-x)P(x)2. Previous transport, NMR, specific heat, and magnetic penetration depth measurements have provided compelling evidence for the presence of a quantum critical point (QCP) near optimal superconductivity at x=0.3. H...
متن کاملHigh-temperature superconductivity in lattice-expanded C60.
C60 single crystals have been intercalated with CHCl3 and CHBr3 in order to expand the lattice. High densities of electrons and holes have been induced by gate doping in a field-effect transistor geometry. At low temperatures, the material turns superconducting with a maximum transition temperature of 117 K in hole-doped C60/CHBr3. The increasing spacing between the C60 molecules follows the ge...
متن کاملSuppression of the antiferromagnetic pseudogap in the electron-doped high-temperature superconductor by protect annealing
In the hole-doped cuprates, a small number of carriers suppresses antiferromagnetism and induces superconductivity. In the electron-doped cuprates, on the other hand, superconductivity appears only in a narrow window of high-doped Ce concentration after reduction annealing, and strong antiferromagnetic correlation persists in the superconducting phase. Recently, Pr(1.3-x)La0.7Ce(x)CuO4 (PLCCO) ...
