Anomalous Hall resistance in Ge:Mn systems with low Mn concentrations
Shengqiang Zhou, Danilo Buerger, Manfred Helm +1
Taking Mn doped Germanium as an example, we evoke the consideration of a two-band-like conduction in diluted ferromagnetic semiconductor (FMS). The main argument for claiming Ge:Mn…
Spinel ferrite nanocrystals embedded inside ZnO: magnetic, electronic and magneto-transport properties
Shengqiang Zhou, K. Potzger, Qingyu Xu +8
In this paper we show that spinel ferrite nanocrystals (NiFe2O4, and CoFe2O4) can be texturally embedded inside a ZnO matrix by ion implantation and post-annealing. The two kinds o…
Non-DMS related ferromagnetism in transition metal doped zinc oxide
Kay Potzger, Shengqiang Zhou
We review pitfalls in recent efforts to make a conventional semiconductor, namely ZnO, ferromagnetic by means of doping with transition metal ions. Since the solubility of those el…
Crystallographically oriented Co and Ni nanocrystals inside ZnO formed by ion implantation and postannealing
Shengqiang Zhou, K. Potzger, J. von Borany +4
In the last decade, transition-metal-doped ZnO has been intensively investigated as a route to room-temperature diluted magnetic semiconductors (DMSs). However, the origin for the…
Fe-implanted ZnO: Magnetic precipitates versus dilution
Shengqiang Zhou, K. Potzger, G. Talut +9
Nowadays ferromagnetism is often found in potential diluted magnetic semiconductor systems. However, many authors argue that the observed ferromagnetism stems from ferromagnetic pr…
Ferromagnetism and suppression of metallic clusters in Fe implanted ZnO - a phenomenon related to defects?
Shengqiang Zhou, K. Potzger, G. Talut +7
We investigated ZnO(0001) single crystals annealed in high vacuum with respect to their magnetic properties and cluster formation tendency after implant-doping with Fe. While metal…
