The technology of preparation of polycrystal CeB4 samples by arc melting is developed and they are obtained. The complex study of thermal and transport properties of oriented single crystal HoB4, ErB4 та TmB4 samples is performed. The magnetic phase diagrams for these compounds are constructed. The oriented single crystal HoB4, ErB4, TmB4 and LuB4 samples are prepared and transferred to ILTPE NASU for effect dHvA study Product Description popup.authors popup.nrat_date 2020-04-02 Close
