Magneto-electronic properties and spin-resolved I-V curves of a Co/GeSe heterojunction diode: an ab initio study
(Springer, 2013-05)
We present ab initio calculations of magnetoelectronic and transport properties of the interface of hcp Cobalt (001) and the intrinsic narrow-gap semiconductor germanium selenide (GeSe). Using a norm-conserving pseudopotentials ...
How reliable are Hanle measurements in metals in a three-terminal geometry?
(American Institute of Physics, 2013-05)
We test the validity of Hanle measurements in three-terminal devices by using aluminum (Al) and gold (Au). The obtained Hanle and inverted Hanle-like curves show an anomalous behavior. First, we measure Hanle signals 8 ...
Landau-Zener and Rabi oscillations in the spin-dependent conductance
(Europhysics Letters, 2014-01)
We describe the spin-dependent quantum conductance in a wire where a magnetic eld is spatially modulated. The change in direction and intensity of the magnetic eld acts as aperturbation that mixes spin projections. This ...

Spin-resolved local density of states for an Anderson adatom in a ferromagnetic island
(2013-06-01)
In this work, we investigate theoretically the spin-resolved local density of states (SR-LDOS) of a ferromagnetic (FM) island hybridized with an adatom, which is described by the Single Impurity Anderson Model (SIAM). Our ...
Crecimiento y caracterización de películas delgadas de tio2 y ti1- xfexo2
(Universidad Simón Bolívar, 2009-07)
Titanium dioxide (TiO2) and Fe-doped titanium dioxide (Ti1-xFexO2) thin films were grown on silicon substrates using the magnetron sputtering Rf (13.56 MHz) technique. The relevant growth parameters for the samples (pressure, ...
Experimental evidence of enhanced ferroelectricity in Ca doped BiFeO3
(Elsevier B.V., 2014-04-15)
Calcium (Ca)-doped bismuth ferrite (BiFeO3) thin films prepared by using the polymeric precursor method (PPM) were characterized by X-ray diffraction (XRD), field emission gun scanning electron microscopy (FEG-SEM), ...
Combined effects of vertical and lateral confinement on the magnetic properties of MnAs micro and nano-ribbons
(American Institute of Physics, 2016-09)
The micromagnetic domain structure of MnAs films gave place to an intense research activity in the last few years due to its potential application in magneto-electronic devices such as domain-wall track memories and logic ...
