Journal ArticleDOI
Magnetic vortex oscillator driven by d.c. spin-polarized current
Vlad Pribiag,Ilya Krivorotov,Gregory D. Fuchs,Patrick M. Braganca,Ozhan Ozatay,Jack C. Sankey,Daniel C. Ralph,Robert A. Buhrman +7 more
TL;DR: In this paper, the authors demonstrate that a magnetic vortex, isolated within a nanoscale spin-valve structure, can be excited into persistent microwave-frequency oscillations by a spin-polarized d.c. current.
Journal ArticleDOI
Gigahertz Dynamics of a Strongly Driven Single Quantum Spin
TL;DR: By calibrating the spin rotation with an adiabatic passage, the room-temperature “strong-driving” dynamics of a single nitrogen vacancy center in diamond are measured and the breakdown of the rotating wave approximation provides opportunities for time-optimal quantum control of asingle spin.
Journal ArticleDOI
High Dynamic Range Pixel Array Detector for Scanning Transmission Electron Microscopy
Mark W. Tate,Prafull Purohit,Darol Chamberlain,Kayla X. Nguyen,Robert Hovden,Celesta S. Chang,Pratiti Deb,Emrah Turgut,John T. Heron,Darrell G. Schlom,Daniel C. Ralph,Gregory D. Fuchs,Katherine S. Shanks,Hugh T. Philipp,David A. Muller,Sol M. Gruner +15 more
TL;DR: In this paper, a hybrid pixel array detector (EMPAD) is proposed for use in electron microscope applications, especially as a universal detector for scanning transmission electron microscopy, which consists of a 500 µm thick silicon diode array bump-bonded pixel-by-pixel to an application specific integrated circuit.
Journal ArticleDOI
Temperature Dependence of Wavelength Selectable Zero-Phonon Emission from Single Defects in Hexagonal Boron Nitride
N. R. Jungwirth,Brian Calderon,Yanxin Ji,Michael G. Spencer,Michael E. Flatté,Gregory D. Fuchs +5 more
TL;DR: Temperature-dependent results are well described by a lattice vibration model that considers piezoelectric coupling to in-plane phonons and polarization spectroscopy measurements suggest that whereas the 575 nm emission line is directly excited by 532 nm excitation, the 682 nm line is excited indirectly.
Journal ArticleDOI
Spin-transfer effects in nanoscale magnetic tunnel junctions
Gregory D. Fuchs,N. C. Emley,Ilya Krivorotov,Patrick M. Braganca,E. M. Ryan,S. I. Kiselev,Jack C. Sankey,Daniel C. Ralph,Robert A. Buhrman,Jordan A. Katine +9 more
TL;DR: In this paper, it was shown that spin-transfer-driven switching can occur at voltages that are high enough to quench the tunnel magnetoresistance, demonstrating that the current remains spin polarized at these voltages.
