Ferromagnetic Oxide & Unconventional Superconductor Heterostructures for Superconducting Spintronics

超导自旋电子学是自旋电子学（利用电子自旋在设备中）与超导材料的结合。从历史上看，超导和磁性被认为是不相容的现象，但最近纳米制造的发展表明，超导和磁性材料之间的界面可能存在相容性和耦合，并且通过形成自旋极化超电流，两种现象之间更完全的协同作用是可能的。通过沉积铁磁和超导材料的超薄薄膜，我们可以研究发生在它们界面上的基本物理现象，目的是控制和操纵自旋极化超电流，以创造高效的计算设备。在这个博士学位中，我将使用铁磁氧化物和高温非常规超导体来制造异质结构。我将研究在这些材料之间的界面上发生的邻近效应，并探索用非常规超导体制造自旋极化超电流的可能性。深入了解如何用非常规超导体创建和操纵自旋极化超电流对于开发可以在高温下工作的超导自旋电子器件至关重要。该项目与EPSRC-JSPS先进材料基金保持一致。

Superconducting spintronics is the combination of spintronics (the utilisation of electron spin in devices) with superconducting materials. Historically, superconductivity and magnetism were considered incompatible phenomena, but recent developments in nanofabrication have shown that compatibilities and couplings are possible at the interface between superconducting and magnetic materials, and a more complete synergy between the two phenomena is possible through the formation of spin-polarised supercurrents. By depositing ultra-thin films of ferromagnetic and superconducting materials, we can study fundamental physical phenomena occurring at their interfaces, with the aim to control and manipulate spin polarised supercurrents in order to create highly efficient computing devices.In this PhD, I will create heterostructures using ferromagnetic oxides and high-temperature unconventional superconductors. I will investigate the proximity effects occurring at the interfaces between these materials, and explore the possibility of creating spin polarised supercurrents with unconventional superconductors. A thorough understanding of how to create and manipulate spin polarised supercurrents with unconventional superconductors is critical to developing superconducting spintronic devices which can operate at elevated temperatures.This project aligns with an EPSRC-JSPS Advanced Materials Grant.
