Abstract

Controlling the size and distribution of potential barriers within a medium of interacting particles can unveil unique collective behaviors and innovative functionalities. In this study, we introduce a unique superconducting hybrid device using a novel artificial spin ice structure composed of asymmetric nanomagnets. This structure forms a distinctive superconducting pinning potential that steers unconventional motion of superconducting vortices, thereby inducing a magnetic nonreciprocal effect, in contrast to the electric nonreciprocal effect commonly observed in superconducting diodes. Furthermore, the polarity of the magnetic nonreciprocity is in-situ reversible through the tunable magnetic patterns of artificial spin ice. Our findings demonstrate that artificial spin ice not only precisely modulates superconducting characteristics but also opens the door to novel functionalities, offering a groundbreaking paradigm for superconducting electronics.

非对称人工自旋冰超导体混合装置中的磁不互斥性

控制相互作用粒子介质中势垒的大小和分布可以揭示独特的集体行为和创新功能。在这项研究中，我们利用由非对称纳米磁体组成的新型人工自旋冰结构，推出了一种独特的超导混合装置。这种结构形成了一种独特的超导钉势，可引导超导涡旋的非常规运动，从而诱发磁非互惠效应，这与超导二极管中常见的电非互惠效应截然不同。此外，通过人工自旋冰的可调磁性模式，磁性非互惠性的极性是可以就地逆转的。我们的研究结果表明，人造自旋冰不仅能精确调制超导特性，还能开启新功能的大门，为超导电子学提供了一个突破性的范例。
