Abstract :

Thin film resistors, based on the NiCr alloys, have been fabricated and studied at temperatures down to 50 mK. Resistivity of the films varied within (7-11) Ohm*square depending on additions of Cu, Al and Ge. The resistors demonstrate Kondo minimum at 20 K - 30 K. Power dependence measurements at sub Kelvin temperatures showed an electron overheating at the power level above 10 pW for the Ni₇₅Cr₂₀Cu_2.5Al_2.5 (Evanohm) 500 kOhm film resistor.
