摘要：
It is shown that the onset of the third harmonic susceptibility is the only appropriate criterium, when using AC susceptibility measurements, to determine the IL. Then, we show that the IL strongly depends on Be crystallinity of superconductors and on the superconductor volume fraction in the composites. Besides, it is demonstrated, from transport measurements, that the IL corresponds to the J(c) = 0 line.
