We present the resistivity measurements on single crystals of Sr2RuO4-delta, grown by the flux technique. We discuss the striking, linear temperature dependence of resistivity that persists up to similar to 1050 K. The superconductivity in this system is c ...
We have studied the influence of Co and Ni doping on the electronic band structure and the transport properties of high-temperature superconductors. The doping has dramatic effects on both the normal and the superconducting state. Upon doping the residual ...
We show that the average lattice disorder in YBa2Cu3O6.9 films grown by ion-beam sputtering is homogeneous and can be quantified by introducing the lattice coherence length rc that is extracted from the width of X-ray diffraction rocking curves. The superc ...
We used thermal neutron irradiation to produce disorder in Bi-2212 single crystals (T-c = 85 K), at a constant carrier density. The irradiated samples were insulators. High-temperature superconductivity with a lower T-c than prior to irradiation could be r ...
We report on striking sensitivity of the superconducting properties of ion-beam sputtered YBa2Cu3O6.9 films to the lattice disorder (induced by varying growth temperatures). Tc decreases with increasing disorder, while the width of the resistive transition ...
Using angle-resolved photoemission and linearly polarized synchrotron radiation, we measured the electronic band structure of electronic states of CuO2 plane materials ranging from insulators (Sr2CuO2Cl2) to overdoped superconductors (Bi2Sr2CaCu2O8+x). We ...
