Resumen:
The superconducting transition of Nd1.85Ce0.15Cu1+δOy and Sm1.85Ce0.15Cu1+δOy samples was studied as a function of the Cu content through magnetic modulated microwave absorption and resistivity measurements. Superconducting transitions were observed only for samples with a Cu content 1+δ ≥ 1.01. This Cu excess seems to be necessary in order to obtain superconductivity in the electron doped materials.
