摘要: The second harmonic signal, which is generated by co-application of AC and DC fields to polycrystalline type-II superconductors, were analyzed in terms the weak links critical current density. With this aim YBa2Cu3−x Zn x O7−y (x=0, 0.01, 0.02, 0.03, 0.05, and 0.1) samples synthesized order adjust intergranular couplings thus strength links. mechanical magnetic measurements are good agreement on that Zn doping reduces between grains; however, contrary common expectations, it has no direct contribution 2nd signal strength.
