Abstract: Measurements of isothermal magnetization, initial and high-field static susceptibility, and magnetoresistance have been performed at various temperatures on five Ag 100−x Fe x granular films of variable Fe content ͑10 ഛ x ഛ 30͒ obtained by cosputtering. Magnetoresistance and magnetization data have been systematically combined to determine the magnetic correlation volume in each sample and its evolution with temperature and magnetic field. A coherent picture of the whole set of Ag 100−x Fe x films has been obt…
