Magnetooptische Untersuchungen an ferromagnetischen GaMnAs-Epitaxieschichten
Die ferromagnetische Phase von dünnen GaMnAs-Epitaxieschichten, die auf GaAs-Substrat aufgebracht sind und einen Mangan-Gehalt von 1,4-8,5% besitzen werden mit Hilfe des magnetooptischen Kerr-Effektes (MOKE) und des magnetischen Zirkular-Dichroismus (MCD) untersucht. Der Temperaturbereich erstreckt …

Character of the Electronic States Near the Metal -Insulator Transition in Gallium Manganese Arsenide
… here comparing individual defects present in GaMnAs with their properties in a non-magnetic GaAs environment. Mn and other transition metals substituted into the first atomic layer of GaAs by STM manipulation were also studied to observe chemical trends. It is found that the effects of the …

Current-induced torque driven ferromagnetic resonance in magnetic microstructures
This Dissertation explores the interaction between the magnetisation and an alternating current in a uniform ferromagnetic system. Diluted magnetic semiconductors (Ga,Mn)As and (Ga,Mn)(As,P) have been studied. Due to their strong spin-orbit coupling and well-understood band-structure, these …
