The thermal conductivity of post-perovskite (ppv), the highest-pressure polymorph of MgSiO3 in the Earth's mantle, is one of the most important transport properties for providing better constraints on the temperature profile and dynamics at the core-mantle boundary (CMB). Incorporation of Fe ...
We investigate the effect of Fe substitution for Co on the lattice thermal conductivity of CoSb3skutterudites. The polycrystalline materials are formed from uniaxially hot-pressed powders. Three alloys were prepared with 0, 3% and 10% Fe, respectively. Thermal conductivity measurements were made betwee...
The room-temperature thermal conductivity of 1% Ni:La 5Ca 9Cu 24O 41 and 1% Co:La 5Ca 9Cu 24O 41 is approximately 15% smaller than the thermal conductivity of pristine La 5Ca 9Cu 24O 41 thin films of similar thickness. On the other hand, the thermal conductivity of 1% Fe:La 5Ca ...
Compared with pure Fe, the thermal conductivity of Fe0.96Si0.04alloy (blue symbols in Fig.1) at ambient conditions is significantly reduced to 16.5 W m−1 K−1, much lower than the previously estimated light element effects17,20,24. Upon compression, the thermal conductivity increas...

We have measured the ac susceptibility, specific heat, resistivity, and thermal conductivity of single-crystalline samples of FeSi in various temperature ranges between 0.04 and 300 K. The unequivocal result emerges from the ac susceptibility data, and is that there is no evidence for any magnetic...
