Asymmetry of magnetization curves of textured BSCCO
摘要：
测量了织构BSCCO样品的磁化强度与磁场M（H）的关系||c、H||在不同的温度下。在Valkov-Khrustalev模型[V. V. Valkov，B. P. Khrustalev，JETP 80（1995）680]中包含钉扎参数允许成功地描述非对称M（H）依赖性。研究了H的临界电流和钉扎参数与温度和磁场的关系||c和H|| AB估计。
英文摘要：
The dependence of magnetization on magnetic field M(H) was measured for textured BSCCO samples for H || c, H || ab at different temperatures. Inclusion of the pinning parameter in the Valkov-Khrustalev model [V.V. Valkov, B.P. Khrustalev, JETP 80 (1995) 680] allowed to describe successfully the asymmetric M(H) dependencies. The temperature and magnetic field dependencies of critical current and pinning parameter for H || c and H || ab were estimated.
