Abstract
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 B e crystallinity of superconductors and on the superconductor volume fr action in the composites. Besides, it is demonstrated, from transport measurements, that the IL corresponds to the J(c) = 0 line.
