Autor: Yu. F. Markov, K. V. Ponkratov, V. N. Gurin

Publikováno v: Physics of the Solid State. 60:719-722

Monocrystals of lanthanum hexaboride LaB6 containing both natural boron and its isotopes 10B and 11B have been produced using the solution-melt method. Polyelement hexaboride rare-earths have been grown and the corresponding ceramics have been synthe
