We have determined the temperature behaviour of electrical resistivity, thermopower, S, and thermal expansion coefficient, α, for USb2 along both the c and α axes. The Hall effect and the pressure effect on TN up to 0.3 GPa−1 have also been exami

Resistivity of TmGa 3 over paramagnetic range up to 300 K was measured. The magnetic contribution to the resistivity separated exhibits very anomalous behaviour manifested by a pronounced maximum around 30 K. This maximum was interpreted as resulting

A modification of the Van Arkel method is proposed for purification and growth of single crystals of chemical binary compounds. A quartz bulb with a susceptor heated by a high frequency induction coil is used in this method. The uranium and thorium p

Results of the experimentally found temperature dependence of the magnetic resistivity for PrIn 3 are compared with theoretical data for two possible scattering mechanisms. A good quantitative agreement between theory and experiment is observed at lo

The possibility of the occurrence of a maximum in the temperature dependence of the electrical resistivity in the paramagnetic phase of singlet ground state crystal field materials is examined theoretically on the basis of an earlier developed formal

The experimentally determined magnetic contributions to the total resistivity of NdIn 3 and NdSn 3 compounds have been compared with those calculated in the first Born approximation. For NdSn 3 the satisfactory agreement between theory and experiment

(Th x U 1−x ) 3 As 4 solid solutions were obtained in the range 1 ≥ x ≥ 0.85 by the modified Van Arkel method. Their resistivity, thermopower and Hall constant were determined in temperatures 4.2—700 K. The condition of impurity band formatio

The accuracy with which the thermopower of short specimens can be measured has been studied as a function of specimen dimensions and the method of mounting. Techniques are described which are capable of 2% accuracy for 1 mm long specimens.
