Electrical resistivity, magnetoresistivity, and the Hall effect have been studied in a topological semimetal WTe2 single crystal in the temperature range from 12 to 200 K under magnetic fields up to 9 T. It has been found that quadratic temperature dependences of the electrical resistivity in the absence of a magnetic field and the conductivity in a magnetic field are observed at low temperatures, which is apparently associated with contributions from various scattering mechanisms. Single-band and two-band models were used to analyze data on the Hall effect and magnetoresistivity. These results indicate electron-hole compensation with a slight predominance of electron charge carriers., 9 pages, 7 figures

Представлен обзор многокомпонентных металлических сплавов (принципов их легирования, условий синтеза, структуры, фазового состава, физико-механических свойств). Рассмотрены особенности легирования и фазовых превращений в алюминиевых сплавах, полифункциональных низкомодульных медных и титановых сплавах и интерметаллидах, интерметаллических соединениях на основе никеля (фаз Гейслера). A review of multicomponent metal alloys (principles of their alloying, synthesis conditions, structure, phase composition, physical and mechanical properties) is presented. The features of alloying and phase transformations in aluminum alloys, multifunctional low-modulus copper and titanium alloys and intermetallides, intermetallic compounds based on nickel (Geisler phases) are considered.
