The Y1−xYbx/2Gdx/2Ba2Cu3O7−y superconducting samples for x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared by using the solid-state reaction technique. Resistivity measurements of the samples were performed in QD–PPMS system under different magnetic fields up to 5 T in zero fields cooling regime. Using the resistivity data, the upper critical magnetic field Hc2(0) at T = 0 K for 50% of Rn was calculated by the extrapolation Hc2(T) to the temperature T = 0 K. The coherence length in T = 0 K were calculated from Hc2(0) and the effects of x in the composition on both the coherence length and the upper critical magnetic field were examined. The results showed that Hc2(0) varied from 84.05 to 122.26 T with the content x. The upper critical magnetic field in the temperature T = 0 K slightly decreased with increasing the content x. Using the content x, the upper critical magnetic field can be controlled and this can be used in the superconductivity applications.
