摘要:

本文研究了具有非谐电流-相位关系的SNINS型超导结(S为超导体,N为正常金属,I为绝缘体)在临界温度附近外磁场中的行为。考虑了在较宽的电子透射系数值范围内,最大电流与磁通量值的关系。此外,它是如何研究的相干长度的尺度中的任意厚度的正常层的存在下,在超导区域中的杂质的存在下,影响的灵敏度的最大电流的磁场大小。

英文摘要:

The behaviour of superconducting junctions of SNINS-type (where S is superconductor, N is normal metal, I is insulator) with anharmonic current-phase relations in the external magnetic field near the critical temperature was investigated. The dependence of the maximum current on the value of the magnetic flux in a wide range of electron transmission coefficient values was considered. Also, it was investigated how the presence of a normal layer of an arbitrary thickness in the scale of coherence length and in the presence of impurities in superconducting regions affect the sensitivity of the maximum current to the magnetic field magnitude.
