Ultrathin perpendicular free layers for lowering the switching current in STT-MRAM
Tiffany S. Santos, Goran Mihajlovic, Neil Smith +4
The critical current density required for switching the magnetization of the free layer (FL) in a spin-transfer torque magnetic random access memory (STT-MRAM) cell is pro…
Origin of the resistance-area product dependence of spin transfer torque switching in perpendicular magnetic random access memory cells
Goran Mihajlovic, Neil Smith, Tiffany Santos +5
We report on an experimental study of current induced switching in perpendicular magnetic random access memory (MRAM) cells with variable resistance-area products (RAs). Our result…
Insights into ultrafast demagnetization in pseudo-gap half metals
Andreas Mann, Jakob Walowski, Markus Münzenberg +8
Interest in femtosecond demagnetization experiments was sparked by Bigot's discovery in 1995. These experiments unveil the elementary mechanisms coupling the electrons' temperature…
Measurement of Gilbert damping parameters in nanoscale CPP-GMR spin-valves
Neil Smith, Matthew J. Carey, Jeffrey R. Childress
In-situ, device level measurement of thermal mag-noise spectral linewidths in 60nm diameter CPP-GMR spin-valve stacks of IrMn/ref/Cu/free, with reference and free layer of similar…
Rapid Domain Wall Motion in Permalloy Nanowires Excited by Spin-Polarized Current Applied Perpendicular to the Nanowire
C. T. Boone, J. A. Katine, M. Carey +3
We study domain wall (DW) dynamics in permalloy nanowires excited by alternating spin-polarized current applied perpendicular to the nanowire. Spin torque ferromagnetic resonance m…
Co-resonant enhancement of spin-torque critical currents in spin-valves with synthetic-ferrimagnet free-layer
Neil Smith, Stefan Maat, Matthew J. Carey +1
It is experimentally shown that the critical current for onset of spin-torque instability in current-perpendicular-to-plane spin-valves can be strongly enhanced using "synthetic fe…
