Type of article: Article

Summary

A short overview of two recently discovered series of high-critical temperature superconductors is given. The first one deals with copper oxycarbonates which exhibit critical temperatures up to 82 K. Their structural principle is based on the fact that rows of CO3 groups can assure the connection between either octahedral or pyramidal copper layers forming new intergrowths with critical temperatures superior to those of the mother structures. The second family concerns the mercury-based cuprates, characterized by critical temperatures ranging from 27 to 132 K.
