Superparamagnetic response of Fe-coated W tips in spin-polarized scanning tunneling microscopy
Soo-hyon Phark, Jeison A. Fischer, Marco Corbetta +2
We performed spin-polarized scanning tunneling spectroscopy on biatomic-layer-high Co nanoislands grown on Cu(111) in magnetic fields oriented normal to the sample surface, with Fe…
Dynamics of magnetic domain wall motion after nucleation: Dependence on the wall energy
Keiki Fukumoto, Wolfgang Kuch, Jan Vogel +5
The dynamics of magnetic domain wall motion in the FeNi layer of a FeNi/Al2O3/Co trilayer has been investigated by a combination of x-ray magnetic circular dichroism, photoelectron…
Influence of domain wall interactions on nanosecond switching in magnetic tunnel junctions
Jan Vogel, Wolfgang Kuch, Riccardo Hertel +8
We have obtained microscopic evidence of the influence of domain wall stray fields on the nanosecond magnetization switching in magnetic trilayer systems. The nucleation barrier in…
Interplay between magnetic anisotropy and interlayer coupling in nanosecond magnetization reversal of spin-valve trilayers
Jan Vogel, Wolfgang Kuch, Julio Camarero +7
The influence of magnetic anisotropy on nanosecond magnetization reversal in coupled FeNi/Cu/Co trilayers was studied using a photoelectron emission microscope combined with x-ray…
