Gadolinium diffusion-doping for enhancing activation energy in superconducting YBa2Cu3O7−x

Investigation of effect of x in Yb1-xGdxBa2Cu3O7-ysuperconducting structures on upper critical magnetic field and coherence length

“…Although numerous studies have been undertaken on the pinning properties of melt processed Yb123 [6] with finely dispersed Y211, the effect of x in Yb 1-x Gd x Ba 2 Cu 3 O 7 polycrystalline structure on the activation energy and the c-lattice parameter [7,8], the effect of x of Y 1-x Gd x/2 Yb x/2 Ba 2 Cu 3 O 7 superconducting structures on the activation energy [9] and the upper critical magnetic field [10], the effect of Gd diffusion into Y123 [11,12], and Yb diffusion into Y123 [13], no studies on the effect of x in such Yb 1-x Gd x Ba 2 Cu 3 O 7-y polycrystalline superconducting structure on the upper critical magnetic field and the coherence length have been reported.…”
