摘要：

We report resistivity and AC susceptibility measurements under external magnetic field in NdCeCuO single crystals. From resistivity data we have estimated the upper critical fields, coherence lengths and anisotropy factor; AC susceptibility has allowed the extraction of the activation energy values, which turn out to be higher than the p-type HTSC ones.
