Tailoring the magnetism of GaMnAs films by ion irradiation
Lin Li, S. D. Yao, Shengqiang Zhou +10
Ion irradiation of semiconductors is a well understood method to tune the carrier concentration in a controlled manner. We show that the ferromagnetism in GaMnAs films, known to be…
The importance of hole concentration in establishing carrier-mediated ferromagnetism in Mn doped Ge
Shengqiang Zhou, Danilo Bürger, Wolfgang Skorupa +3
In the present work, we have prepared Mn-doped Ge using different annealing approaches after Mn ion implantation, and obtained samples with hole concentrations ranging from 10^18 t…
Landau levels and magnetopolaron effect in dilute GaAs:N
P. M. Krstajić, M. Helm, F. Peeters
The magnetic-field dependence of the energy spectrum of GaAs doped with nitrogen impurities is investigated. Our theoretical model is based on the phenomenological Band Anticrossin…
Hysteresis in the magneto-transport of Manganese-doped Germanium: evidence for carrier-mediated ferromagnetism
Shengqiang Zhou, Danilo Buerger, Arndt Muecklich +6
We report the fabrication of Ge:Mn ferromagnetic semiconductors by Mn-ion implantation into Ge followed by pulsed laser annealing. Benefiting from the short time annealing, the hol…
