The preparation of Ni-Co powder for magnetoresistive sensors was studied. A submicron Ni-Co powder was obtained in good yield by reduction of freshly prepared Ni(II) and Co(II) hydroxides in ethylene glycol. The product was a chemically homogeneous powder alloy with a fcc lattice and a Ni/Co atomic ratio of 70/30. The morphology and the composition of the solid solution are the most suitable for the preparation of thick films for physical sensors.
