Strongly correlated s-wave superconductivity in the N-type infinite-layer cuprate.
Quasiparticle tunneling spectra of the electron-doped ( n-type) infinite-layer cuprate Sr0.9La0.1CuO2 reveal characteristics that counter a number of common phenomena in the hole-doped ( p-type) cuprates. The optimally doped Sr0.9La0.1CuO2 with T(c) = 43 K exhibits a momentum-independent superconducting gap Delta = 13.0+/-1.0 meV that substantially exceeds the BCS value, and the spectral charac...
متن کامل1 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...
متن کاملNodeless superconducting phase arising from a strong (π, π) antiferromagnetic phase in the infinite-layer electron-doped Sr(1-x)La(x)CuO2 compound.
The asymmetry between electron and hole doping remains one of the central issues in high-temperature cuprate superconductivity, but our understanding of the electron-doped cuprates has been hampered by apparent discrepancies between the only two known families: Re(2-x)Ce(x)CuO4 and A(1-x)La(x)CuO2. Here we report in situ angle-resolved photoemission spectroscopy measurements of epitaxially stab...
متن کاملObservation of vortices and hidden pseudogap from scanning tun- neling spectroscopic studies of electron-doped cuprate supercon- ductor Sr0.9La0.1CuO2
We present the first demonstration of vortices in an electron-type cuprate superconductor, the highest Tc (= 43 K) electron-type cuprate Sr0.9La0.1CuO2. Our spatially resolved quasiparticle tunneling spectra reveal a hidden low-energy pseudogap inside the vortex core and unconventional spectral evolution with temperature and magnetic field. These results cannot be easily explained by the scenar...
متن کاملMagnetic resonance in the spin excitation spectrum of electron-doped cuprate superconductors.
We study the emergence of a magnetic resonance in the superconducting state of the electron-doped cuprate superconductors. We show that the recently observed resonance peak in the electron-doped superconductor Pr0.88LaCe0.12CuO4-delta is consistent with an overdamped spin exciton located near the particle-hole continuum. We present predictions for the magnetic-field dependence of the resonance ...
