Nanostructures displaying fluorescence and magnetic properties at the same time are potentially useful for achieving simultaneous bio-sepn. and bio-sensing (e.g., magnetic sepn. coupled with multiplexing optical detection of different tumor cell population ...
The spin-dependent transport in multiwall carbon nanotubes, obtained by chemical vapour deposition in porous alumina membranes, has been investigated. The zero-bias anomaly is shown to follow the typical power law GT(-alpha) (eV/kT). In the nanotubes conta ...
In this thesis we study various effects of magnetism in proximity structures, composed of superconducting electrodes in contact with a normal metal. Magnetism can be present in the system through the Zeeman and the orbital coupling. Proximity structures of ...
Patterned magnetic thin films are of interest due to the potential for new technological applications and also because of their modified physical behaviour as the lateral dimensions are reduced. The functionality of patterned films can be intelligently des ...
Conventional Hall devices are widely employed to measure magnetic fields produced by millimetre sized (or larger) current-caring conductors or permanent magnets with a standard active area of about (100 um)^2. Micro-Hall sensors have recently emerged as a ...
A quasi one-dimensional model of spin transport in heterogeneous media based on the Boltzmann equation is presented in order to define the basic properties characterizing perpendicular spin transport in nanostructures. Experimental results are reviewed, fi ...
Here we introduce a novel neutron imaging method, which is based on the effect that the spatial coherence of the neutron wave front can be changed through small-angle scattering of neutrons at magnetic domain walls in the specimen. We show that the techniq ...
We investigate the non-adiabaticity of current-induced domain wall motion by time resolved analysis of thermally activated domain wall motion between two metastable states within a Co/Pt multilayer wire with a strong uniaxial perpendicular anisotropy. By m ...
The aim of this thesis work was to obtain a deeper understanding of spin-dependent transport by the study of mixed effects of heat and charge currents in magnetic nanostructures. Indeed, even thermodynamics establish a relationship between both currents, n ...
Tailored nonmagnetic semiconductor-metal hybrid structures exhibit a large magnetoresistance effect in a homogeneous magnetic field. This is the so-called extraordinary magnetoresistance effect. Here, we study numerically the magnetoresistance of such hybr ...
