Spinel ferrite nanocrystals embedded inside ZnO: magnetic, electronic and magneto-transport perperties

Zhou, S.; Potzger, K.; Xu, Q.; Kuepper, K.; Talut, G.; Shalimov, A.; Mäucklich, A.; Helm, M.; Fassbender, J.; Arenholz, E.; Schmidt, H.

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 ferrite nanocrystals show comparable magnetization with corresponding bulk ferrites. Anomalous Hall effect and positive magnetoresistance have been observed. Our study suggests a ferrimagnet/semiconductor hybrid system for potential applications in magneto-electronics. This hybrid system can be tuned by selecting different transition metal ions (from Mn to Zn) to obtain various magnetic and electronic properties.
