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 T_N ∼ 285 K. T_N 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 T_c is 32 K at x = 0.15.
