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…

Spin-dependent transport in nanocomposite C:Co films
Shengqiang Zhou, Markus Berndt, Danilo Buerger +10
The magneto-transport properties of nanocomposite C:Co (15 and 40 at.% Co) thin films are investigated. The films were grown by ion beam co-sputtering on thermally oxidized silicon…

Ferromagnetic transition metal implanted ZnO: a diluted magnetic semiconductor?
Shengqiang Zhou, K. Potzger, Qingyu Xu +7
Recently theoretical works predict that some semiconductors (e.g. ZnO) doped with magnetic ions are diluted magnetic semiconductors (DMS). In DMS magnetic ions substitute cation si…
