Effect of lithographically-induced strain relaxation on the magnetic domain configuration in microfabricated epitaxially grown Fe81Ga19
R. P. Beardsley, D. E. Parkes, J. Zemen +10
We investigate the role of lithographically-induced strain relaxation in a micron-scaled device fabricated from epitaxial thin films of the magnetostrictive alloy Fe81Ga19. The str…
Optical orientation of spins in GaAs:Mn/AlGaAs quantum wells via impurity-to-band excitation
P. V. Petrov, I. A. Kokurin, Yu. L. Ivanov +5
The paper reports optical orientation experiments performed in the narrow GaAs/AlGaAs quantum wells doped with Mn. We experimentally demonstrate a control over the spin polarizatio…
Antiferromagnetic multi-level memory cell
V. Schuler, K. Olejnik, X. Marti +9
Antiferromagnets (AFs) are remarkable magnetically ordered materials that due to the absence of a net magnetic moment do not generate dipolar fields and are insensitive to external…
Optical determination of the Neel vector in a CuMnAs thin-film antiferromagnet
V. Saidl, P. Nemec, P. Wadley +12
Recent breakthroughs in electrical detection and manipulation of antiferromagnets have opened a new avenue in the research of non-volatile spintronic devices. Antiparallel spin sub…
Imaging current-induced switching of antiferromagnetic domains in CuMnAs
M. J. Grzybowski, P. Wadley, K. W. Edmonds +9
The magnetic order in antiferromagnetic (AF) materials is hard to control with external magnetic fields. However, recent advances in detecting and manipulating AF order electricall…
Inertial displacement of a domain wall excited by ultra-short circularly polarized laser pulses
T. Janda, P. E. Roy, R. M. Otxoa +9
Domain wall motion driven by ultra-short laser pulses is a prerequisite for envisaged low-power spintronics combining storage of information in magneto electronic devices with high…
