We have measured its complex AC susceptibility as a function of temperature and found that below Tc there are two distinguishable superconducting 'phases'.

文摘It has been recently discovered that the sintered Y1Ba2Cu3O7-x, compound is an architypical high critical temperature （Tc） superconductor with a perovskite structure. We have measured its complex AC susceptibility as a function of temperature and found that below Tc there are two distinguishable superconducting 'phases'.
