Thermal and electrical properties of Evanohm and other resistance alloys below 4 K

The specific heat c of Evanohm resistance wire has been measured to be c=0.037+0.333 T J⋅kg−1⋅K−1 between 0.15 and 1.5 K. The thermal conductivity λ of Evanohm is given by λ=0.020 T+0.048 T2 W⋅m−1⋅K−1 in the same temperature range. These results are compared with similar measurements for constantan, manganin, Nichrome, and a platinum–tungsten alloy. The electrical and magnetic properties of these materials are also reviewed.
