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…
Ion beam modification of magnetic tunnel junctions
B. M. S. Teixeira, A. A. Timopheev, N. Caçoilo +6
The impact of 400 keV ion irradiation on the magnetic and electrical properties of in-plane magnetized magnetic tunnel junction (MTJ) stacks was investigated by ferromagneti…
A platform for time-resolved scanning Kerr microscopy in the near-field
Paul S. Keatley, Thomas H. J. Loughran, Euan Hendry +4
Time-resolved scanning Kerr microscopy (TRSKM) is a powerful technique for the investigation of picosecond magnetization dynamics at sub-micron length scales by means of the magnet…
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…
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…
