平面缺陷钉扎磁通晶格和CDW中的有序和蠕变

Order and Creep in Flux Lattices and CDWs Pinned by Planar Defects

Aleksandra Petkovic, Thomas Nattermann

摘要:

从理论上研究了第二类超导体及相关系统中随机分布的点杂质\emph{and}平面缺陷对有序和输运的影响。对于相同取向的平面缺陷的磁通线晶格表现出一个新的玻璃相占主导地位的平面缺陷有限的可压缩性,横向迈斯纳效应,大样本的磁化率和指数衰减的平移长程序footuations。平行于缺陷的电流$J$的磁通蠕变电阻率为$ρ(J)\sim \exp-(J_0/J)^{3/2}$。强烈的无序性迫使一系列位错松弛剪切应变。

英文摘要:

The influence of randomly distributed point impurities \emph{and} planar defects on the order and transport in type-II superconductors and related systems is considered theoretically. For planar defects of identical orientation the flux line lattice exhibits a new glassy phase dominated by the planar defects with a finite compressibility, a transverse Meissner effect, large sample to sample fuctuations of the susceptibility and an exponential decay of translational long range order. The flux creep resistivity for currents $J$ parallel to the defects is $ρ(J)\sim \exp-(J_0/J)^{3/2}$ . Strong disorder enforces an array of dislocations to relax shear strain.
