Unconventional superconductivity in electron-doped layered Li0.48(THF)yHfNCL.

We report magnetic susceptibility measurements on a layered superconductor Li0.48(THF)0.3HfNCl having Tc approximately 26 K. The present study revealed that (a) the Fermi level density of states is small, N*(EF) approximately 0.25 states/(eV spin f.u.), (b) mass enhancement is negligible, gamma; approximately 1, (c) electron-phonon coupling is weak, lambda(ep)<<1, (d) exchange enhancement is ne...

1 Superconductivity and spin fluctuations in the electron - doped infinitely - layered high

We report Cu NMR studies on uniaxially aligned and unaligned powder samples of an electron-doped infinitely-layered high Tc cuprate superconductor Sr0.9La0.1CuO2 (Tc =42 K). We measured the nuclear spin-lattice relaxation rate 1/T1 up to 800 K. We found from the temperature dependence of 1/T1T that the wave-vector-averaged spin susceptibility is highly enhanced by spin-fluctuations in the norma...

Nonlinear Electron-Phonon Coupling in Doped Manganites.

We employ time-resolved resonant x-ray diffraction to study the melting of charge order and the associated insulator-to-metal transition in the doped manganite Pr_{0.5}Ca_{0.5}MnO_{3} after resonant excitation of a high-frequency infrared-active lattice mode. We find that the charge order reduces promptly and highly nonlinearly as function of excitation fluence. Density-functional theory calcul...

Electron Orbital Angular Momentum and Spin- Orbit Coupling in Superconductivity

Received DOI: 2 Superconductivity arises when solids have conducting bands (singly occupied wave functions) that do not have electron-nuclear scattering (Fermi contact) and the temperature is low enough to eliminate partial wave scattering of electrons. This means that the conducting bands do not include s basis functions (atomic quantum numbers l ,m = 0), and the temperature is low enough so t...
