Abstract

A phase diagram for the boron-doped new superconductor Sr2CuO2(CO3)1-x(BO3) x has been systematically investigated. The parent compound Sr2CuO2(CO3) is an antiferromagnetic (AF) insulator with a Néel temperature of TN ∼ 285 K. TN of Sr2CuO2(CO3)1-x(BO3) x changes drastically with increasing boron content x. In the lightly doped AF state (0 ≤ x ≤ 0.04), the strong superexchange interaction within the CuO2-layers still yields a long-range AF ordering. The superconductivity is confined to the narrow compositional range 0.04 ≤ x ≤ 0.15 and its highest Tc is 32 K at x = 0.15.
