Temperature-sensitive thick-film systems based on spinel-type NiMn2O4-CuMn2O4-MnCo2O4 manganites with p-and p+-types of electrical conductivity were obtained. All elements are shown good electrophysical characteristics before and after long-term ageing test at 170 °C. It is shown that in two-layer p-p+ systems are typical increases of electrical resistance during ageing test, while three-layer type p-p+-p structures are high stabile.
