Investigation of effect of x in Yb1-xGdxBa 2Cu3O7-y superconducting structures on upper critical magnetic field and coherence length
(Institute of Physics Publishing, 2009)
The resistivity measurements of the Yb1-xGdxBa 2Cu3O7-y superconducting samples prepared by using the solid-state reaction technique for x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were performed in QD-PPMS system under different ...
Anomalous ferromagnetic behaviour of Y2O3 and CuO nanoparticles in YBa2Cu3Oy superconductor
(Institute of Physics Publishing, 2009)
Anomalous ferromagnetic behaviour of the Y2O3 and CuO components in YBa2Cu3Oy (Y123) was observed after severe reduction of particle size. The particle size reduction was performed in following way: Y2O3, BaCO3 and CuO ...
