SUPERCONDUCTIVITY UP TO 64-K IN THE COPPER OXYFLUORIDES SR2-XAXCUO2F2+DELTA (A=CA, BA) PREPARED USING NH4F AS A FLUORINATING REAGENT

We report here a simple and efficient synthetic route to high-temperature superconducting oxyfluorides. Solid phase fluorination of Sr2CuO3 with NH4F at relatively low temperatures produces superconducting Sr2CuO2F2+δ; this simple preparation route eliminates the need for F2 gas. Importantly, as-syn...
