Abstract : The de Haas-van Alphen effect has been measured in single crystals of ytterbium at 1.2 degrees K in magnetic fields up to 116 koe. The crystals, prepared by distillation, were found to be in either a hexagonal or a f.c.c. phase at room temperature but only in the hexagonal phase after a cooling cycle to 1.2 degrees K. The hexagonal phase is attributed to a hexagonal-close-packed structure reported previously for ytterbium at temperatures above 260 degrees C. De Haas-van Alphen frequencies for the h.c.p. principal planes and symmetry directions are reported. These results indicate hyperbolic sections of the Fermi surface of h.c.p. ytterbium. (Author)
