Demonstrating magnetic memory in iron-rhodium structures using a quantum diamond microscope
Kristine V. Ung, Gregory M. Stephen, Nicholas A. Blumenschein +7
Iron-rhodium (FeRh) has a first-order phase transition near room temperature between antiferromagnetic (AFM) and ferromagnetic (FM) phases, making it a promising material for magne…
Evidence of a Hybridized Topological State in Weyl Semimetal/Topological Insulator MnSn/BiSb Heterostructures
Ryan T. Van Haren, Gillian P Boyce, Gregory M. Stephen +4
We report magnetotransport evidence of a hybridized Weyl semimetal (WSM) Fermi arc/topological insulator (TI) surface state at the interface of a ferromagnetic MnSn…
Transport Enhancement and In Situ Control of Electronic Correlation via Photoinduced Modulation Doping of van der Waals Heterostructures
Collin R. Sanborn, Son T. Le, Thuc T. Mai +7
Modulation doping, a well-established technique for traditional semiconductor heterostructures, is a promising approach for tailoring carrier concentration in 2D materials devices.…
Spatially-resolved voltage-reversal due to Bernoulli potentials in dissipative BiSrCaCuO
Sharadh Jois, Gregory M. Stephen, Samuel W. LaGasse +3
We measure magneto-transport and critical currents in BiSrCaCuO Hall bar devices. Above critical current in an applied magnetic field, we observe longitudinal d…
Magnetic Field-Mediated Superconducting Logic
Alexander J. Edwards, Son T. Le, Nicholas W. G. Smith +7
While superconductors are highly attractive for energy-efficient computing, fundamental limitations in their logic circuit integration have hindered scaling and led to increased en…
Direct Comparison of Static and Dynamic Measurements of Spin Generation in a Topological Insulator Thin Film
Vinay Sharma, Sharadh Jois, Ryan Van Haren +6
The competition between intrinsic spin-orbit physics, magnetic phenomena, and the quality of materials and interfaces governs the charge-to-spin conversion processes that are essen…
