Fe-ITO granular films with various volume fractions of Fe were prepared using the radio frequency (RF) co-sputtering technique. The magnetic and magnetoresistance properties were investigated. A transition from superparamagnetic granular films to ferromagnetic multidomain granular films with increasing the volume fraction of Fe is observed. The magnetoresistance of sample with low volume fraction of Fe follows (M/MS)2, while the magnetoresistance of samples with high volume fraction of Fe is composed of a ferromagnetic and a superparamagnetic contribution that is likely caused by the presence of small isolated superparamagnetic granules and interconnected or larger granules of ferromagnetic Fe. Further morphological and crystallographic analysis is required to fully establish the explanation.
