Magnetic states at the Oxygen surfaces of ZnO and Co-doped ZnO
N. Sanchez, S. Gallego, M. C. Munoz
First principles calculations of the O surfaces of Co-ZnO show that substitutional Co ions develop large magnetic moments which long-range coupling depends on their mutual distance…
Magnetoresistance in Thin Permalloy Film (10nm-thick and 30-200nm-wide) Nanocontacts Fabricated by e-Beam Lithography
Nicolas Garcia, Cheng Hao, Lu Yonghua +7
In this paper we show spin dependent transport experiments in nanoconstrictions ranging from 30 to 200nm. These nanoconstrictions were fabricated combining electron beam lithograph…
Spin injection in a single metallic nanoparticle: a step towards nanospintronics
A. Bernand-Mantel, P. Seneor, N. Lidgi +8
We have fabricated nanometer sized magnetic tunnel junctions using a new nanoindentation technique in order to study the transport properties of a single metallic nanoparticle. Cou…
Magnetism and half-metallicity at the O surfaces of ceramic oxides
S. Gallego, J. I. Beltran, J. Cerda +1
The occurence of spin-polarization at ZrO, AlO and MgO surfaces is proved by means of \textit{ab-initio} calculations within the density functional theory. Large…
