Abstract
Resistive materials with resistivity (ρ) of 5.0 to 689.9×10-8 Ωm and temperature coefficient of resistance (TCR) of 1749 to 4948×10-6 K-1 were successfully fabricated by using the stacking and rolling of metallic sheets of Fe and Cu. The Fe/Cu multilayer structure showed changes of electrical characteristics with the direction of accumulating and the number of sheets accumulating. The TCR values of the specimens decreased with increase of the number of accumulating layers at the parallel direction for current flow. The resistivity of the specimens increased with increase of the number of accumulating layer at the series direction for current flow. This process allows the electrical characteristics to be controlled as required, and the resistance material of a precise resistor for current detection to be made.
