Dependency of c-lattice parameter, activation energy and its magnetic power constant on x in Y1−xYbx/2Gdx/2Ba2Cu3O7−y superconductors

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

“…Our previous study was about the effects of content x in Y 1-x Yb x/2 Gd x/2 Ba 2 Cu 3 O 7 (Y, Yb, Gd)123 structure on the upper critical magnetic field and coherence length [10]. It was found in our previous study that Yb123 phase in this composition has stronger interactions and Gd123 has weaker interactions compared to Y123.…”

“…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.…”
