Nanoscale Domain Wall Dynamics in Micromagnetic Structures with Weak Perpendicular Anisotropy
Tim A. Butcher, Nicholas W. Phillips, Abraham L. Levitan +4
Time-resolved pump-probe soft X-ray ptychography and Scanning Transmission X-ray Microscopy (STXM) were employed to study the magnetic domain wall dynamics in microstructures of pe…
Room temperature realization of artificial chiral magnets with reprogrammable magnon nonreciprocity at zero field
Mingran Xu, Axel J. M. Deenen, Huixin Guo +1
Chiral magnets are materials which possess unique helical arrangements of magnetic moments, which give rise to nonreciprocal transport and fascinating physics phenomena. On the one…
Competing anisotropies in the chiral cubic magnet CoZnMn unveiled by resonant x-ray magnetic scattering
Victor Ukleev, Oleg I. Utesov, Chen Luo +11
The cubic -Mn-type alloy CoZnMn is a chiral helimagnet that exhibits a peculiar temperature-dependent behavior in the spiral pitch, which decreases from 130 nm at ro…
Steerable current-driven emission of spin waves in magnetic vortex pairs
Sabri Koraltan, Katrin Schultheiss, Florian Bruckner +4
The efficient excitation of spin waves is a key challenge in the realization of magnonic devices. We demonstrate the current-driven generation of spin waves in antiferromagneticall…
