Magnetic field-induced exchange effects between Mn ions and free carriers in ZnSe quantum well through the intermediate nonmagnetic barrier studied by photoluminescence
D. M. Zayachuk, T. Slobodskyy, G. V. Astakhov +5
Photoluminescence (PL) of the 50 nm / nm / 2.5 nm / 30 nm structures is investigated as a f…
Lithographic engineering of anisotropies in (Ga,Mn)As
S. Hümpfner, M. Sawicki, K. Pappert +6
The focus of studies on ferromagnetic semiconductors is moving from material issues to device functionalities based on novel phenomena often associated with the anisotropy properti…
Very large magnetoresistance in lateral ferromagnetic (Ga,Mn)As wires with nanoconstrictions
C. Ruester, T. Borzenko, C. Gould +7
We have fabricated (Ga,Mn)As nanostructures in which domain walls can be pinned by sub-10 nm constrictions. Controlled by shape anisotropy, we can switch the regions on either side…
Large magnetoresistance effect due to spin-injection into a non-magnetic semiconductor
G. Schmidt, G. Richter, P. Grabs +3
A novel magnetoresistance effect, due to the injection of a spin-polarized electron current from a dilute magnetic into a non-magnetic semiconductor, is presented. The effect resul…
