Equilibrium intermediate-state patterns in a type-I superconducting slab in an arbitrarily oriented applied magnetic field
摘要：
研究了平板I型超导体中超导畴和正常畴的平衡拓扑。相对于以前的工作的重要改进是：（1）的能量的外部磁场，作为变形的超导畴的存在下，以同样的方式计算三种不同的拓扑结构，和（2）计算所施加的字段的任意取向。的相图的最小能量的拓扑结构作为施加的场的大小和角度的函数。对于小（大）的应用领域正常（超导）管被发现，而对于中间领域平行域具有较低的能量。场的幅度的范围，超导管结构是有利的收缩时，场是更多的面内取向。
英文摘要：
The equilibrium topology of superconducting and normal domains in flat type-I superconductors is investigated. Important improvements with respect to previous work are: (1) the energy of the external magnetic field, as deformed by the presence of superconducting domains, is calculated in the same way for three different topologies, and (2) calculations are made for arbitrary orientation of the applied field. A phase diagram is presented for the minimum-energy topology as a function of applied field magnitude and angle. For small (large) applied fields normal (superconducting) tubes are found, while for intermediate fields parallel domains have a lower energy. The range of field magnitudes for which the superconducting-tubes structure is favored shrinks when the field is more in-plane oriented.
