Temperature Range

Measurements of the magnetic susceptibility of a powdered sample of VTe in the temperature range 90 - 700 K, and of the a.c. electrical conductivity (σ), thermoelectric power (θ) and dielectric constant (ε′) of pressed pellets of the compound in the temperature range 300 -1100 K are reported. The compound is found to be antiferromagnetic with Neel temperature 420 ± 5 K. The effective paramagnetic moment and paramagnetic Curie temperature are found to be 1.6 μB and - 250 K, respectively. The dependence of σ, θ and ε′ on temperature shows no anomaly at the Neel temperature and is indicative of the metallic nature of the compound.

Radiation Induced

Electrical conductivity measurements were made for the determination of G (free ions) in some hydrocarbons. The radiation source was a x-ray tube operated at 55 kV. Four quantities were measured for each liquid: 1. the stationary electrical conductivity at low electric field strength during irradiation, 2. the mobilities of the radiation-induced ions, 3. the volume recombination coefficient, and 4. the absorbed dose rate.All measurements were performed with aerated liquids at room temperature. The following G-values were obtained: n-pentane 0,1; n-hexane and n-heptane 0,09; iso-octane 0,11; cyclohexane 0,06; benzene 0,07; decalin 0,04. The standard deviation was estimated to ± 25 per cent.
