Suppression of spectral gap and flat bands on a cuprate superconductor side-surface

Abstract Side surfaces of cuprate superconductors are expected to display a suppressed d -wave order parameter and zero-energy topological flat bands with a large density of states, making them susceptible to symmetry broken orders. Yet such surfaces have never been investigated...

Opportunities toward Scalable Domain-Wall-Based Spintronic Devices

Abstract Since its initial proposal in 2004, racetrack memory, which utilizes current-induced motion of domain walls within a magnetic nanowire, has evolved from a conceptual spintronic device into a mature research platform supported by major advances in materials engineering, n...

Spontaneous emergence of skyrmions beyond room temperature in boron-doped CrTe

Abstract Magnetic skyrmions are vortex-like spin textures that exhibit remarkable emergent phenomena and hold great promise for applications in spintronics, magnonic devices, and neuromorphic computing. Typically, these spin textures are formed in magnetic samples through the app...
