Thermal conductivity of the amorphous alloy Fe₄₀Ni₄₀P₁₄B₆between 80 and 300 K

Abstract

The thermal conductivity of the amorphous alloy Fe40Ni40P14B6 is investigated with the aim to separate out the lattice contribution and to compare it with that of amorphous dielectrics. The problems of the influence of the radiative transfer of heat between the sample and its environment, which causes errors in the determination of thermal conductivity, are discussed. The authors found that the temperature dependence of the lattice thermal conductivity of the alloys is qualitatively the same as that of amorphous dielectrics.
