Structural and magnetic dynamics of a laser induced phase transition in FeRh
S. O. Mariager, F. Pressacco, G. Ingold +11
We use time-resolved x-ray diffraction and magnetic optical Kerr effect to study the laser induced antiferromagnetic to ferromagnetic phase transition in FeRh. The structural respo…
Nonuniform current density and spin accumulation in a 1 μm thick n-GaAs channel
Bernhard Endres, Mariusz Ciorga, Robert Wagner +6
The spin accumulation in an n-GaAs channel produced by spin extraction into a (Ga,Mn)As contact is measured by cross-sectional imaging of the spin polarization in GaAs. The spin po…
Observation of non-linear magnetic vortex gyration by X-ray microscopy and micromagnetic simulations
Arne Vansteenkiste, Ben Van de Wiele, Markus Weigand +7
Magnetic vortex gyration in a 500 nm wide, 50 nm thick Permalloy square platelet was investigated using time-resolved scanning transmission x-ray microscopy and micromagnetic simul…
Antiferromagnetic coupling across silicon regulated by tunneling currents
R. R. Gareev, M. Schmid, J. Vancea +6
We report on the enhancement of antiferromagnetic coupling in epitaxial Fe/Si/Fe structures by voltage-driven spin-polarized tunneling currents. Using the ballistic electron magnet…
Spin-orbit coupling effect in (Ga,Mn)As films: anisotropic exchange interactions and magnetocrystalline anisotropy
S. Mankovsky, S. Polesya, S. Bornemann +4
The magneto-crystalline anisotropy (MCA) of (Ga,Mn)As films has been studied on the basis of ab-initio electronic structure theory by performing magnetic torque calculations. An ap…
