抜粋

In this work we report experimental results concerning the influence of potassium and excess copper additions on the AC complex susceptibility and microstructural development within polycrystalline YBCO high-temperature superconductors with nominal composition Y_1-0.2xBa_2-0.2xK_xCu₃O_y (x = 0-1.20). The real (X′) and the imaginary (X″) parts of the complex magnetic susceptibility of YBCO were recorded as a function of the temperature at various magnetic fields up to 10 Oe. From these data the intergranular critical current densities were calculated using Bean's critical state model. A proper concentration x, which is approximately equal to x = 0.40 in the initial Y1-_0.2xBa_2-0.2xK_xCu₃O_y batch was found to improve the Josephson coupling between the grains.
