摘要: Abstract The lattice parameter of Ba 0.6 K 0.4 BiO 3 , which is a well-studied conventional superconductor, was measured by the X-ray Rietveld method between 10 K and room temperature. A very small change in could be detected superconducting phase. attributed to spontaneous strain generated phase coupling order strain. It concluded that this phenomenon common all superconductors.
