A simple formulation for magnetoresistance in metal-insulator granular films with increased current
(2013) [Journal article]We studied the tunnel magnetoresistance in metal/insulator granular films when the applied current is varied. The tunnel magnetoresistance shows a strong modification related to a non-Ohmic behaviour of theses materials. ... -
Turn on of new electronic paths in Fe-SiO2 granular thin film
(2014) [Journal article]The electrical properties of Fe-SiO2 have been studied in the low-field regime (eDV kBT), varying the injected current and the bias potential. Superparamagnetism and a resistance drop of 4400X (for a voltage variation of ...
