Magneto-transport properties of CoFe-Al2O3 granular films in the vicinity of the percolation threshold
Source abstract
Abstract
Abstract Granular films (Co 50 Fe 50 ) x -(Al 2 O 3 ) 1− x deposited on glass substrates by dual electron beam evaporation were studied for their magneto-transport properties. Isotropic tunneling magnetoresistance (TMR) up to 10% at room temperature in magnetic fields up to 5 T was found for the compositions just below the percolation threshold ( x c ). Different types of temperature dependencies of TMR below and above x c are analyzed.
