摘要:

超导体中钉扎力的不均匀分布导致磁化不对称。建立了考虑超导体内部场分布的模型,拟合了多孔织构Bi_{1.8} Pb_{0.3} Sr_{1.9} Ca_{2} Cu_{3} O_{x}的对称和非对称磁化曲线.发现在小于一定尺寸的晶体中,热平衡磁化的实现依赖于温度和磁场。

英文摘要:

Inhomogeneous distribution of the pinning force in superconductor results in a magnetization asymmetry. A model considering the field distribution in superconductor was developed and symmetric and asymmetric magnetization loops of porous and textured Bi_{1.8}Pb_{0.3}Sr_{1.9}Ca_{2}Cu_{3}O_{x} were fitted. It is found that the thermal equilibrium magnetization realizes in crystals smaller than some size depending on temperature and magnetic field.
