| Summary: | 博士 === 國立清華大學 === 物理研究所 === 82 === The Tc of Ba1-xKxBiO3 depends on the solubility of Potassium.
In superconducting range, Tc increases and then decreases. of
Oxygen also decreases its Tc. The structures all belong to3m
space group. In YBaCu3-xFexOy crystal Fe replaces Cu(2) site.
TlBaPrCu2Oysed with Rietveld theory.It''s space group is P4/mmm.
a=3.9184, c=12.5498 Angstrum.
