Abstract
The geometry of the intermediate state (IS) flux structures in type-I superconductors, observed during early stages of magnetic flux penetration induced by an externally applied perpendicular magnetic field, is analysed using the concept of minimal surfaces. This approach is based on the assumption that local free energy minimization, for each individual flux structure, dominates when the magnetic flux regions are sufficiently spatially separated; that is, when the global free energy minimization predicts very low periodicity in the intermediate state of the sample.
期刊介绍：
Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity.
The main goal of the journal is to publish:
1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods.
2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance.
3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices.
The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
