Direct evidence for neutrino flavor transformation from neutral-current interactions in the Sudbury Neutrino Observatory.
Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported, providing strong evidence for solar nu(e) flavor transformation.
Nonlocal magnetization dynamics in ferromagnetic heterostructures
Two complementary effects modify the GHz magnetization dynamics of nanoscale heterostructures of ferromagnetic and normal materials relative to those of the isolated magnetic constituents. On the one…
Enhanced gilbert damping in thin ferromagnetic films.
The precession of the magnetization of a ferromagnet is shown to transfer spins into adjacent normal metal layers, slowing down the precession corresponding to an enhanced Gilbert damping constant in the Landau-Lifshitz equation.
Measurement of day and night neutrino energy spectra at SNO and constraints on neutrino mixing parameters.
The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates, and a global solar neutRino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.
Spin pumping and magnetization dynamics in metallic multilayers
We study the magnetization dynamics in thin ferromagnetic films and small ferromagnetic particles in contact with paramagnetic conductors. A moving magnetization vector causes ‘‘pumping’’ of spins…
Magnetization switching through giant spin-orbit torque in a magnetically doped topological insulator heterostructure.
The giant SOT and efficient current-induced magnetization switching exhibited by the bilayer heterostructure may lead to innovative spintronics applications such as ultralow power dissipation memory and logic devices.
Blowing magnetic skyrmion bubbles
A phase diagram for skyrmion formation is determined and the efficient manipulation of these dynamically created skyrMions, including depinning and motion, are revealed, which could lead to progress in sk Kyrmion-based spintronics.
