In: Proceedings of International Conference on Magnetism, ICM 76. - : Elsevier. - 072040732X - 9780720407327 ; 86-88, s. 796-798

Conference paper (peer-reviewed)abstract
- The Hall resistivity, ρH, of Metglas 2826A is measured for 0.6 ≤ T/Tc ≤ 1.9. Below To (∼255 K), the extraordinary Hall coefficient R1 is constant at +4.24 x x10-8 m3/As. The magnetic susceptibility, derived from our data, exhibits a Curie-Weiss behaviour above 350 K and varies as (T - Tc)-1.75 for (T - Tc) < 90 K. In 2826 at 300 K ρH drops linearly with increasing pressure.

Thermal conductivity of KCl up to 19 kbar
- 1974
-
In: Journal of Physics and Chemistry of Solids. - : Elsevier. - 0022-3697 .- 1879-2553. ; 35:3, s. 421-424
-
Journal article (peer-reviewed)abstract
- The pressure dependency of the thermal conductivity of KCl has been measured at room temperature up to 19 kbar. The high pressure tool was of the “belt” type and a solid medium was used. The specimen was cylindrical and was heated along its axis. The conductivity was found to increase linearly at a rate of (3·3 ± 0·3) per cent/kbar.

Thermal conductivity of NaCl up to 40 kbar and 240-400 K
- 1975

In: High Temperatures-High Pressures. - 0018-1544 .- 1472-3441. ; 7:2, s. 235-239
-
Journal article (peer-reviewed)abstract
- The thermal conductivity, λ, of NaCl has been measured at pressures up to 40 kbar and temperatures between 240 K and 400 K in a solid medium in a 'belt' type of high-pressure apparatus. A steady state method with axial heating of a cylindrical specimen was employed. The increase of lambda with pressure was almost linear and the ratio of the thermal conductivity at 25 kbar to that at atmospheric pressure, λ(25)/λ(0), was found to be 1.72, and independent of temperature within the experimental error.

Thermal conductivity of NaF at high pressures

In: High Temperatures-High Pressures. - 0018-1544 .- 1472-3441. ; 11, s. 339-341
-
Journal article (peer-reviewed)abstract
- The thermal conductivity, λ, of NaF was measured over the pressure range 0-3 GPa at room temperature. An approximately linear variation of λ with P was observed in this range, and the ratio λ(P)/λ(0) was found to be 1.12 for P = 1 GPa.

Electrical resistance of Evanohm under pressure
- 1975
-
In: Review of Scientific Instruments. - : American Institute of Physics (AIP). - 0034-6748 .- 1089-7623. ; 46:9, s. 1292-1293
-
Journal article (peer-reviewed)abstract
- The electrical resistance of Evanohm wire has been determined as a function of hydrostatic pressure. A Teflon cell with a novel type of electrical feedthrough was used to contain the fluid medium. The resistance was found to decrease approximately linearly by 0.3% up to 27 kilobar. The remarkably small variation of its resistance with temperature and pressure makes Evanohm a suitable material for strain measurements under pressure.

Journal article (peer-reviewed)abstract
- The pressure dependence of the thermal conductivity of Araldite has been determined in a cylindrical geometry at 300 K. The pressure coefficient was found to be independent of the percentage of hardener, the conductivity at 25 kbar being higher by the factor 1.75 ± 0.05 than at atmospheric pressure.

Pressure dependence of the thermal conductivity of some polyamides

-
In: Macromolecular Chemistry and Physics. - Basel : Wiley. - 1022-1352 .- 1521-3935. ; 177, s. 271-277
-
Journal article (peer-reviewed)abstract
- The pressure dependence of the thermal conductivities of five polyamides (nylons) have been determined ina cylindrical geometry at 300 K and in the pressure range 0-25 kbar. The conductivities increase strongly with pressure, the values at 25 kbar being higher by the factors 1,83, 1,90, 2,07, and 2,03 for, respectively, nylon 66, nylon 610, nylon 6, nylon 11, and nylon 12, than those at atmospheric pressure. The results are compared with other exerimental results and with theoretical calculations. The difference in conductivity response to pressure between the different varieties is discussed.
