Many neuromorphic hardware technologies are being explored for their potential to increase the efficiency of computing certain problems, and thus facilitate...

Magnetic damping in sputtered Co2MnGe Heusler compounds with A2, B2 and L21 order: Experiment and Theory

March 19, 2018

Author(s):

Justin M. Shaw, Eric R. Edwards, Martin A. Schoen, Michael L. Schneider, Matthew R. Pufall, Thomas J. Silva, Hans T. Nembach, Erna Delczeg

We show that very low values of the magnetic damping parameter can be achieved in sputter deposited poly-crystalline films of Co2MnGe annealed at relatively...

Asymmetric and partial injection locking of a three-terminal spin-torque oscillator

March 09, 2018

Author(s):

Emilie M. Jue, Matthew R. Pufall, William H. Rippard

We measure the injection locking of a three-terminal spin-torque oscillator (STO) excited by a spin-orbit torque. The device consists of a magnetic tunnel...
