Dynamic atomic reconstruction: how Fe3O4 thin films evade polar catastrophe for epitaxy
C. F. Chang, Z. Hu, S. Klein +10
Polar catastrophe at the interface of oxide materials with strongly correlated electrons has triggered a flurry of new research activities. The expectations are that the design of…
Orbital occupation and magnetic moments of tetrahedrally coordinated iron in CaBaFe4O7
N. Hollmann, Z. Hu, Hua Wu +8
CaBaFe4O7 is a mixed-valent transition metal oxide having both Fe2+ and Fe3+ ions in tetrahedral coordination. Here we characterize its magnetic properties by magnetization measure…
Exchange bias in GeMn nanocolumns: the role of surface oxidation
S. Tardif, S. Cherifi, M. Jamet +9
We report on the exchange biasing of self-assembled ferromagnetic GeMn nanocolumns by GeMn-oxide caps. The x-ray absorption spectroscopy analysis of this surface oxide shows a mult…
Evolution of magnetic phases and orbital occupation in (SrMnO3)n/(LaMnO3)2n superlattices
C. Aruta, C. Adamo, A. Galdi +11
The magnetic and electronic modifications induced at the interfaces in (SrMnO)/(LaMnO) superlattices have been investigated by linear and circular magnetic…
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…
Indirect electric field doping of the CuO2 planes of the cuprate NdBa2Cu3O7 superconductor
M. Salluzzo, G. Ghiringhelli, J. C. Cezar +4
The mechanism of field-effect doping in the "123" high critical temperature superconductors (HTS) has been investigated by x-ray absorption spectroscopy in the presence of an elect…
