Scalable Multispecies Ion Transport in a Grid-Based Surface-Electrode Trap
Robert D. Delaney, Lucas R. Sletten, Matthew J. Cich +13
Quantum processors based on linear arrays of trapped ions have achieved exceptional performance, but scaling to large qubit numbers requires realizing two-dimensional ion arrays as…
The interplay of large two-magnon ferromagnetic resonance linewidths and low Gilbert damping in Heusler thin films
William K. Peria, Timothy A. Peterson, Anthony P. McFadden +4
We report on broadband ferromagnetic resonance linewidth measurements performed on epitaxial Heusler thin films. A large and anisotropic two-magnon scattering linewidth broadening…
Suppression of the fieldlike spin-orbit torque efficiency due to the magnetic proximity effect in ferromagnet/platinum bilayers
T. A. Peterson, A. P. McFadden, C. J. Palmstrøm +1
Current-induced spin-orbit torques in CoFeAl/Pt ultrathin bilayers are studied using a magnetoresistive harmonic response technique, which distinguishes the dampinglike and fie…
Spin injection and detection up to room temperature in Heusler~alloy/-GaAs spin valves
T. A. Peterson, S. J. Patel, C. C. Geppert +7
We have measured the spin injection efficiency and spin lifetime in CoFeSi/-GaAs lateral nonlocal spin valves from 20 to 300 K. We observe large (40 V) spin valve s…
Anisotropic spin relaxation in -GaAs from strong inhomogeneous hyperfine fields produced by the dynamical polarization of nuclei
N. J. Harmon, T. A. Peterson, C. C. Geppert +4
The hyperfine field from dynamically polarized nuclei in n-GaAs is very spatially inhomogeneous, as the nu- clear polarization process is most efficient near the randomly-distribut…
Dynamic detection of electron spin accumulation in ferromagnet-semiconductor devices by ferromagnetic resonance
Changjiang Liu, Sahil J. Patel, Timothy A. Peterson +4
A distinguishing feature of spin accumulation in ferromagnet-semiconductor devices is precession of the non-equilibrium spin population of the semiconductor in a magnetic field. Th…
