Growth and processing of single crystal superconducting YBa2Cu3O7−δ
- 56 Downloads
A method for growing millimeter-sized crystals of YBa2Cu3O7−δ is described. Processing conditions were developed to improve the superconducting transition temperature and sharpness, as observed by measurements of the dc magnetic susceptibility. Some of our crystals have been used in observations of the Raman Effect, specific heat, nuclear magnetic resonance, and nuclear quadrupole resonance, with results indicating that the samples are excellent.
