Generation of charge current by the Inverse Stern-Gerlach Effect and the suppression of spin transport due to spin counter-current exchange in semiconductors
Nicholas J. Harmon, Emma Z. Kurth, Dana Coleman +1
The spin-orbit interaction is frequently the mechanism by which spin and charge are coupled for spintronic applications. The discovery of spin, a century ago, relied on spin-charge…
Driving a pure spin current from nuclear-polarization gradients
Nicholas J. Harmon, Michael E. Flatté
A pure spin current is predicted to occur when an external magnetic field and a linearly inhomogeneous spin-only field are appropriately aligned. Under these conditions (such as or…
Theory of oblique-field magnetoresistance from spin centers in three-terminal spintronic devices
Nicholas J. Harmon, Michael E. Flatté
We present a general stochastic Liouville theory of electrical transport across a barrier between two conductors that occurs via sequential hopping through a single defect's spin-0…
Image of dynamic local exchange interactions in the dc magnetoresistance of spin-polarized current through a dopant
Stephen R. McMillan, Nicholas J. Harmon, Michael E. Flatté
We predict strong, dynamical effects in the dc magnetoresistance of current flowing from a spin-polarized electrical contact through a magnetic dopant in a nonmagnetic host. Using…
Tuning Spin Dynamics and Localization Near the Metal-Insulator Transition in Fe/GaAs heterostructures
Yu-Sheng Ou, N. J. Harmon, Patrick Odenthal +3
We present a simultaneous investigation of coherent spin dynamics in both localized and itinerant carriers in Fe/GaAs heterostructures using ultrafast and spin-resolved pump-probe…
Manipulation of the electroluminescence of organic light-emitting diodes via fringe fields from patterned magnetic domains
Nicholas J. Harmon, Michael E. Flatté
We predict very large changes in the room-temperature electroluminescence of thermally-activated delayed fluorescence organic light emitting diodes near patterned ferromagnetic fil…
