Tuning alloy disorder in diluted magnetic semiconductors in high fields to 89 T
S. A. Crooker, N. Samarth
Alloy disorder in II-VI diluted magnetic semiconductors (DMS) is typically reduced when the local magnetic spins align in an applied magnetic field. An important and untested expec…
Internal magnetic fields in thin ZnSe epilayers
S. Ghosh, N. P. Stern, B. Maertz +4
Strain induced spin-splitting is observed and characterized using pump-probe Kerr rotation spectroscopy in n-ZnSe epilayers grown on GaAs substrates. The spin-splitting energies ar…
Current-Induced Polarization and the Spin Hall Effect at Room Temperature
N. P. Stern, S. Ghosh, G. Xiang +3
Electrically-induced electron spin polarization is imaged in n-type ZnSe epilayers using Kerr rotation spectroscopy. Despite no evidence for an electrically-induced internal magnet…
Non-collinear Spin Valve Effect in Ferromagnetic Semiconductor Trilayers
G. Xiang, B. L. Sheu, M. Zhu +2
We report the observation of the spin valve effect in (Ga,Mn)As/p-GaAs/(Ga,Mn)As trilayer devices. Magnetoresistance measurements carried out in the current in plane geometry revea…
Artificial "spin ice" in a geometrically frustrated lattice of nanoscale ferromagnetic islands
R. F. Wang, C. Nisoli, R. S. Freitas +8
We report an artificial geometrically frustrated magnet based on an array of lithographically fabricated single-domain ferromagnetic islands. The islands are arranged such that the…
