标题： Universal Superconductivity in FeTe and All-Iron-Based Ferromagnetic Superconductor Heterostructures

摘要： 铁磁性（FM）和超导性（SC）是两种最著名的宏观量子现象。 然而，自然界通常不允许SC和FM共存而不出现显著退化。 在这里，我们介绍了第一个完全基于铁的SC/FM异质结构，由Fe（Te，Se）和Fe3GeTe2组成，并表明在这个平台上，强铁磁性和高温超导性可以稳健共存。 随后，我们发现相邻层的化学邻近效应可以普遍地将原本不具有超导性的FeTe薄膜驱动到超导态。 这表明FeTe的基态非常接近超导态，可以通过各种其他扰动将其驱动进入或退出超导态。 总的来说，这表明基于Fe-Te的异质结构提供了一个独特的机会来操控磁性、超导性和拓扑物理，为新的超导技术铺平了道路。 显示英文摘要

摘要： Ferromagnetism (FM) and superconductivity (SC) are two of the most famous macroscopic quantum phenomena. However, nature normally does not allow SC and FM to coexist without significant degradation. Here, we introduce the first fully iron-based SC/FM heterostructures, composed of Fe(Te,Se) and Fe3GeTe2, and show that in this platform strong FM and high-temperature SC robustly coexist. We subsequently discover that chemical proximity effect from neighboring layers can universally drive the otherwise non-superconducting FeTe films into a SC state. This suggests that the ground state of FeTe is so close to the SC state that it could be driven in and out of the SC state with various other perturbations. Altogether, this shows that Fe-Te-based heterostructures provide a unique opportunity to manipulate magnetism, superconductivity and topological physics, paving the way toward new superconducting technologies.
