Memory effect of MnGe nanomagnets embedded inside a Mn-diluted Ge matrix
Shengqiang Zhou, Artem Shalimov, Kay Potzger +5
Crystalline Mn5Ge3 nanomagnets are formed inside a Mn-diluted Ge matrix using Mn ion implantation. A temperature-dependent memory effect and slow magnetic relaxation are observed b…
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…
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…
Suppression of secondary phase formation in Fe implanted ZnO single crystals
K. Potzger, Shengqiang Zhou, H. Reuther +5
Unwanted secondary phases are one of the major problems in diluted magnetic semiconductor creation. Here, the authors show possibilities to avoid such phases in Fe implanted and po…
