Preparation and some properties of HxREBa2CU3O7 (RE= Er, Nd, Dy, Ho, Gd) superconductors

  • 1. Brookhaven National Lab., Upton, NY (USA). Dept. of Applied Science

Description

Hydrogen gas has been found to react directly with the subject oxides. Most exhibit a small region of H solid solubility which remains superconducting with a slight increase in critical temperature (1-2K). At higher H contents a hydrogen rich hydride phase which is amorphous precipitates. The H rich phases are not superconducting at 4K or above. Neutron diffraction studies of D1.55YBa2Cu3O7 confirm that the D rich phase is amorphous, but that its precipitation causes increased microtwinning in the D saturated oxide. (orig.)
