Threefold onset of vortex loops in superconductors with a magnetic core

Mauro M. Doria, Antonio R. de C. Romaguera, M. V. Milošević, F. M. Peeters

摘要:

超导体内部的磁性包裹体产生了一个迷人的{ \it涡旋环}复合体。我们的计算,在Ginzburg-Landau理论的框架下完成,揭示了{ \it环总是成核的三重态}周围的磁芯。在介观超导球中,最终的超导态的特征在于那些受限的涡旋环和最终弹到球表面的涡旋环,演化成穿透样品表面的{ \it涡旋对}。

英文摘要:

A magnetic inclusion inside a superconductor gives rise to a fascinating complex of {\it vortex loops}. Our calculations, done in the framework of the Ginzburg-Landau theory, reveal that {\it loops always nucleate in triplets} around the magnetic core. In a mesoscopic superconducting sphere, the final superconducting state is characterized by those confined vortex loops and the ones that eventually spring to the surface of the sphere, evolving into {\it vortex pairs} piercing through the sample surface.
