Transmission Electron Miscroscopy Observation of the Decomposition of YBa 2 Cu 4 O 8 into YBa 2 Cu 3 O 7-δ and CuO

The decomposition of Yba 2 Cu 4 O 8 (Y-124) into Yba 2 Cu 3 O 7-δ (Y-123) and CuO at high temperatures has been expected to create Y-123 with finely dispersed CuO precipitates suitable for flux pinning. In fact, samples of thermally decomposed Y-124 exhibit a critical current density, J c , which is...
