Tunneling magnetoresistance in granular cermet films with particle size distribution

Description

The correlation between tunneling magnetoresistance (TMR) and field sensitivity (dMR/dH) for granular films (Co50Fe50)x-(Al2O3)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/dH was found for the compositions just below the percolation threshold
