摘要
计算了双结超导π环、零环及规则超导环阵列的自由能随外加磁场及温度的变化,给出了超导转变温度附近的系统相图。针对高温超导体及低温超导体中出现的顺磁迈斯纳效应,用π结、零结概念,给出了一种简单的理论解释。
We calculated the free energy of superconducting rings with two junction and superconducting ring array under different external magnetic fields, and offered the phase branch diagram of the system within a range near the superconducting transition temperature. A theory of π junction and 0 junction was developed to explain the paramagnetic Meissner effect in both low Tc and high Tc superconductors.
