Abstract

A series of (YCa)Ba2Cu4O8 superconducting compounds has been synthesized at ambient oxygen pressure. A zero-resistance Tc of 76 K is obtained with the as-grown YBa2Cu4O8. In Y0.925Ca0.075Ba2Cu4O8, Tc is enhanced to 83 K, producing a transport critical current density of 190 A/cm2 at 77 K.
