The thermal conductivities and electrical resistivities of Tb, Dy, Gd, Ho, Er, and Yb polycrystals were measured as a function of temperature between 90 and 300 K. The results confirm the anomalies at the magnetic transition temperatures. The thermal

A detailed investigation of the thermal conductivity of pure, heavy rare-earth metals has been made in the range of temperatures 0.3–4.2 K. The results obtained on the 10 samples investigated (Gd, Dy, Ho, Er, Yb, and Tb) show that the thermal condu

We report a study of using the waste heat from a window-type air-conditioner to heat water for domestic use. Results show 401 of water can be heated to about 90°C in about 312h and the room cools faster when the water heating system is introduced th

The thermal conductivity of polycrystalline ytterbium between 90K and 300K was found to increase with temperature. The additional contribution to the thermal conductivity is likely to be due to the bipolar term.

The thermal conductivity of gadolinium, measured between 0.4 and 4.2°K, can be separated into a linear ( T ) and a quadratic ( T 2 ) contribution. The Lorentz number, as estimated from the linear term, agrees well with the theoretical value. Tentati
