Ion irradiation effects on a magnetic Si/Ni/Si trilayer and lateral magnetic-nonmagnetic multistrip patterning by focused ion beam
B. N. Dev, N. Banu, J. Fassbender +5
Fabrication of a multistrip magnetic/nonmagnetic structure in a thin sandwiched Ni layer [Si(5 nm)/Ni(10 nm)/Si] by a focused ion beam (FIB) irradiation has been attempted. A contr…
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…
Ferromagnetic, structurally disordered ZnO implanted with Co ions
Kay Potzger, Shengqiang Zhou, Qingyu Xu +6
We present superparamagnetic clusters of structurally highly disordered Co-Zn-O created by high fluence Co ion implantation into ZnO (0001) single crystals at low temperatures. Thi…
Room temperature ferromagnetism in carbon-implanted ZnO
Shengqiang Zhou, Qingyu Xu, Kay Potzger +10
Unexpected ferromagnetism has been observed in carbon doped ZnO films grown by pulsed laser deposition [Phys. Rev. Lett. 99, 127201 (2007)]. In this letter, we introduce carbon int…
Structural and magnetic properties of Mn-implanted Si
Shengqiang Zhou, K. Potzger, Gufei Zhang +9
Structural and ferromagnetic properties in Mn implanted, p-type Si were investigated. High resolution structural analysis techniques like synchrotron X-ray diffraction revealed the…
