Modification of Dzyaloshinskii-Moriya interaction stabilized domain wall chirality by driving currents
G. V. Karnad, F. Freimuth, E. Martinez +7
We measure and analyze the chirality of the Dzyaloshinskii-Moriya interaction (DMI) stabilized spin textures in multilayers of Ta/CoFeB/MgO. The effective DMI…
Study of energetics of 360° domain walls through annihilation
G. V. Karnad, E. Martinez, M. Voto +4
The Dzyaloshinskii-Moriya interaction (DMI) causes domain walls in perpendicular magnetized systems to adopt a homochiral configuration by winding in the same direction for both Up…
Effect of annealing on the interfacial Dzyaloshinskii-Moriya interaction in Ta/CoFeB/MgO trilayers
R. A. Khan, P. M. Shepley, A. Hrabec +4
The interfacial Dzyaloshinskii-Moriya interaction (DMI) has been shown to stabilize homochiral Néel-type domain walls in thin films with perpendicular magnetic anisotropy and as a…
Tunneling magneto thermo power in magnetic tunnel junction nanopillars
N. Liebing, S. Serrano-Guisan, K. Rott +4
We study the tunneling magneto thermo power (TMTP) in CoFeB/MgO/CoFeB magnetic tunnel junction nanopillars. Thermal gradients across the junctions are generated by a micropatterned…
Universality of Spectator Fragmentation at Relativistic Bombarding Energies
A. Schuettauf, W. D. Kunze, A. Woerner +45
Multi-fragment decays of 129Xe, 197Au, and 238U projectiles in collisions with Be, C, Al, Cu, In, Au, and U targets at energies between E/A = 400 MeV and 1000 MeV have been studied…
Interfacial Dzyaloshinskii-Moriya interaction in Ta\Co20Fe60B20\MgO nanowires
R. Lo Conte, E. Martinez, A. Hrabec +10
We report current-induced domain wall motion (CIDWM) in Ta\Co20Fe60B20\MgO nanowires. Domain walls are observed to move against the electron flow when no magnetic field is applied,…
