Abstract

The effect of depositing CdS nanoparticles on the surface of a high-temperature superconductor Bi–Pb–Sr–Ca–Cu–O is investigated by means of magnetically modulated microwave absorption spectroscopy (MAMMAS), for the 77–300 K temperature range. The experimental results indicate that the onset of superconducting transition in Bi–Pb–Sr–Ca–Cu–O/CdS composite is shifted to high temperature, with regard to the single superconductor sample; and it is associated to the presence of new superconducting phase in the interface between the superconductor micrograins and the CdS nanoparticles. Additionally, the low-field microwave absorption (LFMA) at liquid nitrogen temperature is used to confirm the superconductor state of these materials.
