Low Temperature Properties of the Orientationally Disordered Material: Cyanide-Doped Potassium Bromide
Low temperature properties of KBr doped with different concentrations of CN have been measured from 0.030K to 10K. The specific heat, thermal conductivity, and dielectric susceptibility are found to vary greatly with the concentration of CN. The concentrations 1%, 3%, 10%, 20%, and 50% CN were …

Influence of Structural Relaxation Upon the Low Temperature Properties of Metallic Glasses
We have investigated the low temperature properties of metallic glasses. We find that below 1K, the thermal conductivity of metallic glasses (Fe(,40)Ni(,40)P(,14)B(,6), Pd(,77.5)Si(,16.5)Cu(,6) and Zr(,3)Rh) is similar to that of the large class of amorphous materials previously investigated, …

Thermische Tieftemperatureigenschaften von Seltenerd-Übergangsmetall-Borkarbiden
The present work reports on thermal low-temperature properties of rare earth transition metal borocarbides such as specific heat, thermal conductivity and thermopower. The influence of structural disorder, caused by stoichiometric variations and substitutions of the rare earth element or the …

Low Temperature Behavior of Potassium and Sodium-Silicate Glasses
The low-temperature properties of a system of well characterized potassium and sodium silicate glasses have been measured in an effort to better understand the nature of the low-energy excitations which exist in all glasses and to further investigate relationships between the low-temperature …

Low temperature, glass-like properties of crystalline beta-alumina
The low temperature properties measured for single crystal Na, Ag, K, and Li B-alumina are characteristic of those found in amorphous materials. The specific heat is dominated below 1 K by a term approximately linear in temperature instead of the cubic dependence normal for crystals. All except K …

The influence of structural relaxation upon the low-temperature thermal conductivity of ancient natural glasses
It has been observed that the experimental low-temperature ( <lOK) properties of glasses depend upon a sample's thermal history. Apparently, the intrinsic glassy excitations (TLS) which dominate the low-temperature properties of glasses are affected by the structural relaxation which occurs in a …
