The aim of this thesis work is to study the spin-dependent transport in multiwalled carbon nanotubes (MWNT). To do so, the electrical resistance of MWNT contacted between ferromagnetic electrodes has been measured, as a function of the contacts magnetic co ...
The reactive liquid infiltration (RLI) technique, applied to-the MgB2 material, has allowed us to obtain either bulk or wire samples of good transport properties. The evaluation of the voltage-current characteristics, V-I-n, for typical samples, measured b ...
We propose a model of transport in thick-film resistors which naturally explains the observed nonuniversal values of the conductance exponent t extracted in the vicinity of the percolation transition. Essential ingredients of the model are the segregated m ...
We propose a theory of the origin of transport nonuniversality in disordered insulating-conducting compounds based on the interplay between microstructure and tunneling processes between metallic grains dispersed in the insulating host. We show that if the ...

The continuous time random walk approach for hopping conduction in disordered systems is modified to obtain accurate DC conductivity values over a wide range of hopping site densities. The modification involves eliminating a small fraction of particularly ...
The authors present the percolation and electronic properties of (Y1Ba2Cu3O7-δ)1-xAgx compounds in which silver fills the intergranular space without reducing Tc, which remains at 92±1 K. Normal-state resistivity is decreased by up to two orders of magnitu ...
Electromagnetic levitated and guided systems are commonly used in the field of people transport vehicles, tool machines frictionless bearings and conveyor systems. In the case of low speed people transport vehicles, the electromagnetic levitation offers th ...
