Quantum simulation of ZnO nanowire piezotronics
Leisheng Jin, Lijie Li
We address the problem of quantum transport in a nanometre sized two-terminal ZnO device subject to an external strain. The two junctions formed between the electrodes and the ZnO…
Understanding nanoscale temperature gradients in magnetic nanocontacts
Sébastien Petit-Watelot, Ruben Miguel Otxoa, Mauricio Manfrini +4
We determine the temperature profile in magnetic nanocontacts submitted to the very large current densities that are commonly used for spin-torque oscillator behavior. Experimental…
Agility of vortex-based nanocontact spin torque oscillators
M. Manfrini, T. Devolder, Joo-Von Kim +7
We study the agility of current-tunable oscillators based on a magnetic vortex orbiting around a point contact in spin-valves. Theory predicts frequency-tuning by currents occurs a…
Quantized spin wave modes in magnetic tunnel junction nanopillars
A. Helmer, S. Cornelissen, T. Devolder +4
We present an experimental and theoretical study of the magnetic field dependence of the mode frequency of thermally excited spin waves in rectangular shaped nanopillars of lateral…
Direct current control of three magnon scattering processes in spin-valve nanocontacts
H. Schultheiss, F. Ciubotaru, A. Laraoui +9
We have investigated the generation of spin waves in the free layer of an extended spin-valve structure with a nano-scaled point contact driven by both microwave and direct electri…
