Here we report data on the c -axis resistivity ρ c ( T ) ρc(T) of Nd-LSCO measured as a function of temperature near this QCP, in a magnetic field large enough to entirely suppress superconductivity. Like ρ ab , ρ c ρab,ρc shows an upturn at low temperature, a signature ...
The TSFZ growth of Nd-substituted LSCO (La1.81-xNdxSr0.19CuO4, x=0梅0.4) single crystals has been explored for the first time. Optimal growth parameters have been determined: oxygen pressure 5.5-6.5 bar; CuO-poor solvent (66 mol% CuO) and growth rate 0.6 mm/hour. As a result, high ...
