Abstract
The many de Haas-van Alphen frequencies observed in the hcp transition metal ruthenium have been investigated using the field modulation method in conjunction with a Fourier analysis technique. The observed frequency spectrum is explained in terms of the band structures calculated by Mattheiss for rhenium (also hcp) by invoking the “rigid-band” model. While the correct rhenium band structure is inadequate, that calculated without relativistic corrections can account quantitatively for all the observed frequencies. The details of the size and shape of the smaller pieces of Fermi surface provide a sensitive test for any band structure calculated for ruthenium. The model also explains qualitatively the amplitude behavior of the various frequencies except for some details when magnetic breakdown is operative.
