Readout of a antiferromagnetic spintronics systems by strong exchange coupling of Mn2Au and Permalloy
S. P. Bommanaboyena, D. Backes, L. S. I. Veiga +14
In antiferromagnetic spintronics, the read-out of the staggered magnetization or Neel vector is the key obstacle to harnessing the ultra-fast dynamics and stability of antiferromag…
Direct imaging of chiral domain walls and Néel-type skyrmionium in ferrimagnetic alloys
Boris Seng, Daniel Schönke, Javier Yeste +15
The evolution of chiral spin structures is studied in ferrimagnet Ta/Ir/Fe/GdFeCo/Pt multilayers as a function of temperature using scanning electron microscopy with polarization a…
Quantification of competing magnetic states and switching pathways in curved nanowires by direct dynamic imaging
