Thermodynamics of the Superconducting Phase Transition on High T_c Superconductor RBa₂Cu₃O_y

Department of Physical Chemistry, USTB, Beijing 100083, PRC

摘要: 研究了稀土氧化物高溫超導體RBa₂Cu₃O_y(R:一般為稀土元素)超導轉變的相變性質,認為在沒有外界磁場作用時超導轉變為二級相變,有外界磁場作用時為一級相變。推導出超導體RBa₂Cu₃O_y在超導轉變時體系的Gibbs自由能關系式。

Abstract: The property of superconducting phase transition of the high Tc superconductor RBa₂Cu₃O_y (R:most rare earth elements) was investigated. The conclusion was drawn that the phase transition changed from first order in magnetic field to second order in non-magnetic field. The representation of the Gibbs free energy of the superconductor RBa₂Cu₃O_y at the superconducting-normla state transition in non-magnetic field was derived.
