Superconductivity 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 کاملSuperconductivity upon Co-doping
The crystal structure and physical properties of BaFe2As2, BaCo2As2, and BaNi2As2 single crystals are surveyed. BaFe2As2 gives a magnetic and structural transition at TN = 132(1) K, BaCo2As2 is a paramagnetic metal, while BaNi2As2 has a structural phase transition at T0 = 131 K, followed by superconductivity below Tc = 0.69 K. The bulk superconductivity in Codoped BaFe2As2 below Tc = 22 K is de...
متن کاملSuperconductivity and field-induced magnetism in Pr2-xCexCuO4 single crystals.
We report muon-spin rotation and relaxation (muSR) measurements on single crystals of the electron-doped high-T(c) superconductor Pr2-xCexCuO4. In a zero external magnetic field, superconductivity is found to coexist with dilute Cu spins that are static on the muSR time scale. In an applied field, we observe a mu(+)-Knight shift that is primarily due to the magnetic moment induced on the Pr ion...
متن کاملEnhanced superconductivity by rare-earth metal doping in phenanthrene.
We successfully synthesized La- and Sm-doped phenanthrene powder samples and observed superconductivity in them at T(c) around 6 K. The T(c)s are 6.1 K for La(1) phenanthrene and 6.0 K for Sm(1) phenanthrene, which are enhanced by about 1 and 0.5 K compared to those in A(3) phenanthrene (A = K and Rb) and in Ae(1.5) phenanthrene (Ae = Sr and Ba) superconductors, respectively. The superconductiv...
