The effect of the intergranular couplings on the second harmonic of the fundamental signal, which is generated by co-application of DC and AC fields to a magnetic material having nonlinear magnetization, was investigated on B (2) O (3) doped YBaCuO superconductors. Physical and mechanical properties of B (2) O (3) doped YBaCuO superconductors were also analyzed to support electrical measurements.
