摘要
该文提出一种采用外加直流磁场测量交流磁化率的方法来测量超导体的零场冻结磁通。这种测量方法可采用先加场方式(迈斯纳效应过程)和后加场方式(磁屏蔽过程)两种不同的加场方式测量超导样品的零场冻结磁通。对测量方法进行了分析讨论,给出了对Bi系高温氧化物超导体的测量结果。
This paper recounts a method of measuring zero-field frozen magnetic flux of superconductor which is obtained by measuring a.c.susceptibility of superconductor in applied magnetic field.The zero-field frozen flux can be measured in.two different procedures of Meissner effect and magnetic shielding effect.The method is discussed and experimental results is given for Bi-system high Tc oxide superconductors
