Electrical Switching Dynamics in Circular and Rectangular Ge2Sb2Te5 Nanopillar Phase Change Memory Devices
Ozhan Ozatay, Barry Stipe, Jordan Katine +1
We have measured the critical phase change conditions induced by electrical pulses in Ge2Sb2Te5 nanopillar phase change memory devices by constructing a comprehensive resistance ma…
Spin-Torque-Induced Rotational Dynamics of a Magnetic Vortex Dipole
G. Finocchio, O. Ozatay, L. Torres +3
We study, both experimentally and by numerical modeling, the magnetic dynamics that can be excited in a magnetic thin-film nanopillar device using the spin torque from a spatially…
Scaling Properties of Critical Phase Change Conditions in Ge2Sb2Te5 Nanopillars
O. Ozatay, B. Stipe, J. A. Katine +1

Effects of rf Current on Spin Transfer Torque Induced Dynamics
S. H. Florez, J. A. Katine, M. Carey +3
The impact of radiofrequency (rf) currents on the direct current (dc) driven switching dynamics in current-perpendicular-to-plane nanoscale spin valves is demonstrated. The rf curr…
Strong linewidth variation for spin-torque nano-oscillators as a function of in-plane magnetic field angle
K. V. Thadani, G. Finocchio, Z. -P. Li +6
We measure the microwave signals produced by spin-torque-driven magnetization dynamics in patterned magnetic multilayer devices at room temperature, as a function of the angle of a…
Enhancement in spin-torque efficiency by nonuniform spin current generated within a tapered nanopillar spin valve
P. M. Braganca, O. Ozatay, A. G. F. Garcia +3
We examine the effect a spatially non-uniform spin current with a component polarized partially out of the plane has on a low saturation magnetization nanomagnet free layer. Microm…
