Abstract

An important scientific and technical problem on developing thick resistive granular films used in microelectronics and tool manufacturing is solved. Magnetoresistive Co-containing granular films are obtained by stenciling pastes consisting of microdispersed cobalt boride Co3B and organic binder on a dielectric substrate. Then, the deposited films are heat treated in air with no protection at all. X-ray diffraction analysis and X-ray derivatographic analysis reveal that only ferromagnetic Co (FCC) and amorphous B2O3 are present in the structure of the films at T = 650–850 °C. On this basis, the schedules for the heat treatment of films are devel-oped. The effect of magnetic field on the electric resistance of films is studied
