Friedel oscillations induced surface magnetic anisotropy
A. Szilva, S. Gallego, M. C. Munoz +3
We present detailed numerical studies of the magnetic anisotropy energy of a magnetic impurity near the surface of metallic hosts (Au and Cu), that we describe in terms of a realis…
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…
Intrinsic Superconductivity at 25 K in Highly Oriented Pyrolytic Graphite
P. Esquinazi, N. García, J. Barzola-Quiquia +6
High resolution magnetoresistance data in highly oriented pyrolytic graphite thin samples manifest non-homogenous superconductivity with critical temperature K. These…
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…
Electrostatic Force Microscopy on Oriented Graphite Surfaces: Where Insulating and Conducting Behaviors Coexist
Yonghua Lu, M. Munoz, C. S. Steplecaru +5
We present measurements of the electric potential fluctuations on the surface of highly oriented pyrolytic graphite using electrostatic force and atomic force microscopy. Micrometr…
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…
