论文摘要
在一个简单的模型中考虑了负磁场对薄超导线的影响。这些现象源于两种机制的竞争：顺序参数的波动和准粒子充电不平衡，伴随每个相位滑移事件。第一个过程导致常规的阳性磁性，而第二个机制给出了负贡献。对于由热力学（TAP）和量子波动引起的负磁性电阻的简单分析公式。将理论结果与实验数据进行了比较，并证明了理论和实验之间的良好一致性。
The effect of negative magnetoresistance for thin superconducting wire was considered in a simple model. These phenomena originated from competition of two mechanism: fluctuations of the order parameter and quasiparticles charge imbalance which accompanies each phase slip event. First process results in conventional positive magnetoresistance while the second mechanism gives the negative contributions. Simple analytical formula is obtained for the negative magnetic resistance caused by both the thermodynamics (TAPS) and quantum fluctuations. Theoretical results are compared with experimental data and demonstrate good agreement between theory and experiment.
