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…
Thermal stability for domain wall mediated magnetization reversal in perpendicular STT MRAM cells with W insertion layers
G. Mihajlovic, N. Smith, T. Santos +3
We present an analytical model for calculating energy barrier for the magnetic field-driven domain wall-mediated magnetization reversal of a magneto-resistive random access memory…
Time-domain imaging of curling modes in a confined magnetic vortex and a micromagnetic study exploring the role of spiral spin waves emitted by the core
D. Osuna Ruiz, P. S. Keatley, J. R. Childress +4
The curling spin wave modes of a ferromagnetic vortex confined to a microscale disc have been directly imaged in response to a microwave field excitation using time-resolved scanni…
