Tunneling magnetoresistance in granular cermet films with particle size distribution
Source abstract
Abstract
Abstract The correlation between tunneling magnetoresistance (TMR) and field sensitivity (dMR/d H ) for granular films (Co 50 Fe 50 ) x -(Al 2 O 3 ) 1− x was studied. The position of TMR maximum is shifted towards the lower x in the higher applied magnetic fields. Such a behavior was observed for metal granular nanocomposites but is first reported for granular cermets. However the highest dMR/d H was found for the compositions just below the percolation threshold.
