本文研究了100~300K之间Gd1.8Ba2.4Cu3.4O7-δ(简写为GdBCO)超导体的顺磁性,对GdBCO的磁化强度随磁场和温度的变化分别在100K和0.1T进行了测试,GdBCO的顺磁性遵从朗之万顺磁性理论.在磁光显微镜下,低温12K场冷下,我们观察了从0mT~29mT磁通线进入GdBCO的超导体的过程,以及磁通线在GdBCO超导体中的分布。
We have studied the paramagnetism of Gd1.8Ba2.4Cu3.4O7-δ(abbreviated GdBCO) superconductor during the temperature 100~300K. The magnetization of GdBCO has been tested at 100K and 0. 1T diversified by magnet field and temperature. The paramagnetism of GdBCO has been proved abide by Langevin's paramagnetism law. We have investigated the process of flux entrance in GdBCO superconductor and the flux distribution in GdBCO superconductor.
