Observation of current-induced orbital quadrupole accumulation
Geun-Hee Lee, Yubin Ji, Yongho Park +12
Spintronics and orbitronics rely on current-induced accumulations of magnetic dipoles: spin and orbital angular momentum. However, electronic orbitals inherently carry multipoles b…
Stochastic binary networks with asymmetric and time-delayed interactions
Hantao Zhang, Sidra Gibeault, Matthew W. Daniels +4
Stochastic binary networks are widely used to describe collective dynamics in complex systems and to perform neuromorphic computation, yet realistic networks often contain both asy…
Quantum Spin Transfer of Spin-Correlated Electron Pairs
Seongmun Hwang, Jung Hyun Oh, Paul M. Haney +2
We theoretically investigate quantum spin transfer from spin-correlated conduction-electron pairs to localized spins in a ferromagnet, given that electrons are correlated intrinsic…
Electric Field-Induced Kerr Rotation on Metallic Surfaces
Farzad Mahfouzi, Mark D. Stiles, Paul M. Haney
We use a combination of density functional theory calculations and optical modeling to establish that the electric field-induced Kerr rotation in metallic thin films has contributi…
Strain effects on the fluctuation properties in noncollinear antiferromagnets: a first-principles and macrospin-based study
Mohammad M. Rahman, Farzad Mahfouzi, Matthew W. Daniels +1
We present a theoretical investigation of epitaxial strain effects on the magnetic fluctuation properties of MnSn noncollinear antiferromagnets. Employing density functional th…
Sampling from exponential distributions in the time domain with superparamagnetic tunnel junctions
Temitayo N. Adeyeye, Sidra Gibeault, Daniel P. Lathrop +8
In the superparamagnetic regime, magnetic tunnel junctions switch between two resistance states due to random thermal fluctuations. The dwell time distribution in each state is exp…
Measurement-driven Langevin modeling of superparamagnetic tunnel junctions
Liam A. Pocher, Temitayo N. Adeyeye, Sidra Gibeault +7
Superparamagnetic tunnel junctions are important devices for a range of emerging technologies, but most existing compact models capture only their mean switching rates. Capturing q…
Programmable electrical coupling between stochastic magnetic tunnel junctions
Sidra Gibeault, Temitayo N. Adeyeye, Liam A. Pocher +9
Superparamagnetic tunnel junctions (SMTJs) are promising sources of randomness for compact and energy efficient implementations of probabilistic computing techniques. Augmenting an…
Measurement-driven neural-network training for integrated magnetic tunnel junction arrays
William A. Borders, Advait Madhavan, Matthew W. Daniels +7
The increasing scale of neural networks needed to support more complex applications has led to an increasing requirement for area- and energy-efficient hardware. One route to meeti…
Unbiased Random Number Generation using Injection-Locked Spin-Torque Nano-Oscillators
Nhat-Tan Phan, Nitin Prasad, Abderrazak Hakam +9
Unbiased sources of true randomness are critical for the successful deployment of stochastic unconventional computing schemes and encryption applications in hardware. Leveraging na…
Temperature dependence of the diffusive conductivity of bilayer graphene
Shaffique Adam, M. D. Stiles
Assuming diffusive carrier transport and employing an effective medium theory, we calculate the temperature dependence of bilayer graphene conductivity due to Fermi-surface broaden…
Magnetic dynamics with spin transfer torques near the Curie temperature
Paul M. Haney, M. D. Stiles
We use atomistic stochastic Landau-Lifshitz-Slonczewski simulations to study the interaction between large thermal fluctuations and spin transfer torques in the magnetic layers of…
