Abstract
Magnetoresistance (MR) effects and electroric structure were investigated for granular films employing Co2FeAl0.5Si0.5 (CFAS) alloy. CFAS-MgO granular films showed a maximum MR ratio of approximately 4.8 %. It was however recognized that the surface of CFAS granules was slightly oxidized due to the low formation energy of MgO matrix. By utilizing MgF2 matrix, the MR ratio increased to approximately 6.5 %. After annealing at 200°C, the MR ratio increased slightly. It was thought that the L21 ordered structure was not obtained due to the low annealing temperature. Further annealing at high temperature is required to obtain L21 ordered CFAS granules.
