Abstract

A method for searching and synthesizing new HTSC with higher critical temperatures (Tc) is proposed. It is assumed that an increase in Tc in cuprate superconductors requires not only to increase the number of CuO2 planes in superconducting layers, but also to add fluorine anions to Ca or Y planes. Possible crystal structures and chemical formulas of compounds with higher critical temperatures are proposed.
