摘要：

Thick-film magnetoresistive sensors based on Ni and Co fine powders have shown promising results. In order to improve their performance Ni, Co and Ni-Co powders were prepared by the polyol process. The metallic powders were characterised by simultaneous thermogravimetric and differential thermal analysis (TGA-DTA), X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM).
