Abstract

A series of (YCa)Ba₂Cu₄O₈ superconducting compounds has been synthesized at ambient oxygen pressure. A zero-resistance T_c of 76 K is obtained with the as-grown YBa₂Cu₄O₈. In Y_0.925Ca_0.075Ba₂Cu₄O₈, T_c is enhanced to 83 K, producing a transport critical current density of 190 A/cm² at 77 K.
