New research has actually discovered one-dimensional superconducting stripes at the EuO/KTO( 110) interface, an outcome of the ferromagnetic distance result. This discovery highlights the considerable impact of magnetism on superconducting states and provides a platform for more exploration of high-temperature superconductivity. This study not only advances our understanding of the intricate relationship in between superconductivity and magnetism however likewise showcases the distinct properties of superconducting oxide heterostructures.A group led by Chen Xianhui and Professor Xiang Ziji from the CAS Key Laboratory of Strongly-Coupled Quantum Matter Physics and the Department of Physics at the University of Science and Technology of China, revealed a special superconducting state characterized by one-dimensional superconducting stripes. This state is induced by the ferromagnetic distance effect in an oxide heterostructure comprised of ferromagnetic EuO and (110 )- oriented KTaO3 (KTO). Their findings were published in Nature Physics.The academic neighborhood concurs that the introduction of non-traditional superconducting pairings is elaborately connected to magnetism, especially in copper oxides and iron-based high-temperature superconductors. Magnetic variations are deemed critical in the genesis of high-temperature superconductivity, where the interaction in between superconductivity and magnetism provides increase to superconducting states exhibiting distinct spatial modulation. Superconducting oxide heterostructures including magnetic structural systems become an optimal platform for investigating such superconducting states.Building upon their previous accomplishments, the research group dove much deeper into the superconductivity of this system and its relationship with the ferromagnetic proximity result, thoroughly adjusting the provider concentration of the two-dimensional electron gas living at the interface. They discovered an intriguing in-plane anisotropy in superconductivity amongst samples with low carrier concentrations, which nevertheless vanished in samples showing higher carrier concentrations.Observations of One-Dimensional Superconducting StripesThe superconductivity shift temperature related to the current instructions at the heterojunction interface is caused by the development of one-dimensional superconducting stripes due to the decrease of superconductivity measurement. Meanwhile, anomalous Hall impact and magnetoresistance hysteresis behavior indicate that the coupling in between interfacial conduction electrons and ferromagnetism is affected by band filling. The hybridization of Eu and Ta atomic orbitals within a specific energy variety causes band spin splitting, which follows the experimental outcomes. The introduction of one-dimensional superconducting stripes in EuO/KTO( 110) heterojunction is validated to be caused by the coupling result between superconductivity and magnetism.This research study reveals the existence of a superconducting stripe phase at the EuO/KTO( 110) interface, induced by the ferromagnetic distance impact. It provides the very first unambiguous experimental evidence of exotic superconducting states emerging from the elaborate coupling between superconductivity and magnetism at oxide interfaces.Reference: “Superconducting stripes caused by ferromagnetic distance in an oxide heterostructure” by Xiangyu Hua, Zimeng Zeng, Fanbao Meng, Hongxu Yao, Zongyao Huang, Xuanyu Long, Zhaohang Li, Youfang Wang, Zhenyu Wang, Tao Wu, Zhengyu Weng, Yihua Wang, Zheng Liu, Ziji Xiang and Xianhui Chen, 11 March 2024, Nature Physics.DOI: 10.1038/ s41567-024-02443-x.
