The pressure-induced changes in certain cross sections of the Fermi surface of yttrium have been measured by the de Haas-Van Alphen method. The parameters of the yttrium band structure calculated from these measurements are used to discuss the helicoidal magnetic ordering of heavy rare-earth metals in connection with the Dzyaloshinskii theory (Zh, Eksp.
