Abstract:

In the present work, we have studied the structural, magnetic and magnetoresistive properties of Co-x(SiO2)(100-x) and Co-x(Al2O3)(100-x) composite thin films, obtained by magnetron co-sputtering of metallic and insulator targets. It was shown by transmission electron microscopy and by temperature and field dependences of the magnetization that the films have a fine granular structure. For a wide range of compositions an adequate description was possible in frame of the model of homogeneous non-interacting superparamagnetic hexagonal lattice Co particles. Magnetoresistive sensor prototypes were designed on the base of an optimized magnetoresistive Co-50(Al2O3)(50) composite films
