Synthesis, transport and magnetic properties of Cu-doped apatite Pb10-xCux(PO4)6O
Description
Cu-doped apatite Pb10−xCux(PO4)6O was synthesized. The crystal structure and composition were determined using X-ray diffraction and energy dispersive X-ray spectroscopy. Both the primary phase and impurities have been successfully identified. We performed temperature-dependent resistivity measurements on the synthesized Pb10−xCux(PO4)6O samples. Remarkably, four distinct types of resistivity behaviors were observed in one sample. Following a thorough compositional analysis, we proposed a current percolation model, based on the formation of a Cu/Pb current channel, to elucidate the observed special resistivity behaviors. It is important to note that the Meissner effect was not observed in our magnetization measurements. Consequently, we reached the conclusion that the presence of superconductivity in Cu-doped apatite has yet to be substantiated.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
