X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…
Synthesis and transport properties of epitaxial Bi (111) films on GaAs (111) substrates
Jagannath Jena, Eugene D. Ark, Siddhesh Ambhire +12
In recent decades, the growth of ultrathin epitaxial bismuth (Bi) films on various substrates has garnered interest due to their unique electronic properties. We report upon the gr…
Origin of the Unusual Temperature Dependence of the Upper Critical Field of Kagome Superconductor CsV3Sb5: Multiple Bands or van Hove Singularities?
Ramakanta Chapai, Alexei E. Koshelev, Matthew P. Smylie +8
Van Hove singularities (vHs) located close to the Fermi level in Kagome superconductors AV3Sb5 (A = K, Rb, Cs) have profound influence on their electronic and transport characteris…
A15 Phase Ta3Sb Thin Films: Direct Synthesis, Charge Transport and Spin-Orbit Torque
J. S. Jiang, Qianheng Du, Yi Li +9
Ta3Sb is one of the A15 compounds that have been predicted to have giant spin Hall conductivities due to the gapped Dirac-like band crossings in their electronic structures. We use…
Uniaxial spin texture in a superconducting electron gas revealed by exchange interactions
Junyi Yang, Changjiang Liu, Xianjing Zhou +11
Two-dimensional superconductors with spin-textured Fermi surfaces can be a platform for realizing unconventional pairing states and are of substantial interest in the context of qu…
