Abstract

The LnBa2Cu4O8 superconductors are similar in crystal structure to LnBa2Cu3O7 but contain double rather than single copper-oxygen chains. They have previously been synthesized in bulk form only at high oxygen pressures, and, recently, through the use of reaction rate enhancers. Here we describe for the first time the direct synthesis of ErBa2Cu4O8 and HoBa2Cu4O8 in bulk form at one atmosphere oxygen pressure from simple starting materials.
