Production a characterization of new system superconductor TR3Ba8Cu11Oδ
2016
The production and structural & magnetic characterization of new superconductor system TR:3811 (TR=Sm, Y, Yb) is presented in this work. The samples were produced by the solid state reaction method. The analysis of the measures of the diffraction X-ray, were made with the Rietveld refinement technique, that allowed to infer that the system presents a Pmm2 type structure with the following lattice parameters (a=3.88A, b=3.82A, c=42.82A). The magnetization measurements were made by using the VSM-VERSALAB equipment with a magnetic field variation from a 100Oe to 7000Oe, and a temperature from 50K to 350K, showing the superconducting transition of the order of 90K.
