Abstract
We investigated the formation of superconducting intergrowth phases through the interface reaction both between TlSr2Cu1O5 (Tl-121) and (CrO4)Sr2CuO2, and between Tl -121 and ((CO3)0.5(CrO4)0.5 Sr2CuO2 phases. We found oxychromate intergrowth phases can be formed through the interface reactions and a new superconducting oxychromate compound TlSr4Cu2Oz(CO3)0.5(CrO4)0.5 with Tc above 73 K was discovered based on the results of the interface reactions.
