All Oxide Ferromagnet/Semiconductor Epitaxial Heterostructures
A. Nielsen, A. Brandlmaier, M. Althammer +6
Oxide based ferromagnet/semiconductor heterostructures offer substantial advantages for spin electronics. We have grown (111) oriented Fe3O4 thin films and Fe3O4/ZnO heterostructur…
Epitaxial Zn(x)Fe(3-x)O(4) Thin Films: A Spintronic Material with Tunable Electrical and Magnetic Properties
Deepak Venkateshvaran, Matthias Althammer, Andrea Nielsen +5
The ferrimagnetic spinel oxide Zn(x)Fe(3-x)O(4) combines high Curie temperature and spin polarization with tunable electrical and magnetic properties, making it a promising functio…
Anomalous Hall Effect in Magnetite: Universal Scaling Relation Between Hall and Longitudinal Conductivity in Low-Conductivity Ferromagnets
Deepak Venkateshvaran, Wolfgang Kaiser, Andrea Boger +5
The anomalous Hall effect (AHE) has been studied systematically in the low-conductivity ferromagnetic oxide FeZnO with , 0.1, and 0.5. We used (001), (110),…
Nanosized superparamagnetic precipitates in cobalt-doped ZnO
Matthias Opel, Karl-Wilhelm Nielsen, Sebastian Bauer +6
The existence of semiconductors exhibiting long-range ferromagnetic ordering at room temperature still is controversial. One particularly important issue is the presence of seconda…
