一种检测超导带材的非线性输运方法

A non-linear transport method for detecting superconducting stripes

Rodrigo A. Muniz, Ivar Martin

摘要:

本文从理论上研究了条状超导夹杂物对单晶非线性电阻率的影响。即使当条纹取向在两个正交方向之间的样品由于孪生而变化时,我们预测在相对于晶轴的不同角度测量的非线性电阻率曲线之间应该存在普遍的比例关系。这一预测可用于验证或排除铜氧化物超导体在超导转变温度及以上超导条带的存在。

英文摘要:

We theoretically study the effect of stripe-like superconducting inclusions on the non-linear resistivity in single crystals. Even when the stripe orientation varies throughout the sample between two orthogonal directions due to twinning, we predict that there should be a universal scaling relationship between the nonlinear resistivity curves measured at different angles relative to the crystal axes. This prediction can be used to verify or rule out the existence of superconducting stripes at and above the superconducting transition temperature in cuprate superconductors.
