Superconductivity in single crystals of LaFePO
Single crystals of the compound LaFePO were prepared using a flux growth technique at high temperatures. Electrical resistivity measurements reveal metallic behavior and a resistive transition to the superconducting state at a critical temperature Tc ∼ 6.6 K. Magnetization measurements also show the onset of superconductivity near 6 K. In contrast, specific heat measurements manifest no discont...
متن کاملStatic dipole polarizability of C70 fullerene
The electronic and vibrational contributions to the static dipole polarizability of C70 fullerene are determined using the finite-field method within the density functional formalism. Large polarized Gaussian basis sets augmented with diffuse functions are used and the exchange-correlation effects are described within the Perdew-Burke-Ernzerhof generalized gradient approximation (PBE-GGA). The ...

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 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...
