Nano Lett. 2017 Apr 12;17(4):2367-2373. doi: 10.1021/acs.nanolett.6b05304. Epub 2017 Mar 24.

Charge transport in nanostructures and thin films is fundamental to many phenomena and processes in science and technology, ranging from quantum effects and electronic correlations in mesoscopic physics, to integrated charge- or spin-based electronic circuits, to photoactive layers in...

Modes of periodic domain wall motion in ultrathin ferromagnetic layers.

Physical review letters

Magnetization reversal in a periodic magnetic field is studied on an ultrathin, ultrasoft ferromagnetic Pt/Co(0.5 nm)/Pt trilayer exhibiting weak random domain wall (DW) pinning. The DW motion is imaged by polar magneto-optic Kerr effect microscopy and monitored by superconducting...

Nonadiabatic spin torque investigated using thermally activated magnetic domain wall dynamics.

Physical review letters

Phys Rev Lett. 2010 Jul 30;105(5):056601. doi: 10.1103/PhysRevLett.105.056601. Epub 2010 Jul 29.

Using transmission electron microscopy, we investigate the thermally activated motion of domain walls (DWs) between two positions in Permalloy (Ni80Fe20) nanowires at room temperature. We show that this purely thermal motion is well described by an Arrhenius law, allowing...

We use a pump-probe photoemission electron microscopy technique to image the displacement of vortex cores in Permalloy discs due to the spin-torque effect during current pulse injection. Exploiting the distinctly different symmetries of the spin torques and the Oersted-field...

Phys Rev Lett. 2013 Feb 08;110(6):067203. doi: 10.1103/PhysRevLett.110.067203. Epub 2013 Feb 07.

We determine magnetoresistance effects in stable and clean Permalloy nanocontacts of variable cross section, fabricated by UHV deposition and in situ electromigration. To ascertain the magnetoresistance (MR) effects originating from a magnetic domain wall, we measure the resistance values...

We present a combined theoretical and experimental study, investigating the origin of the enhanced nonadiabaticity of magnetic vortex cores. Scanning transmission x-ray microscopy is used to image the vortex core gyration dynamically to measure the nonadiabaticity with high precision,...

PMID: 33732745
Burns Trauma. 2021 Mar 06;9:tkaa051. doi: 10.1093/burnst/tkaa051. eCollection 2021 Jan.

BACKGROUND: Traffic incidents are still a major contributor to hospital admissions and trauma-related mortality. The aim of this nationwide study was to examine risk-adjusted traffic injury mortality to determine whether hospital type was an independent survival factor.METHODS: Data on...
