Values of C = I ~2 A/Ok~ l-l/e, where A is the area of cross section of theFermi surface normal to kn (the derivative taken for the extremal cross section), have been computed over a wide range of orientations, for several different descriptions of the Fermi surfaces of Cu, Ag, and Au. These values, which are needed for the interpretation of de Haas-van Alphen oscillation amplitudes (see preceding paper), are presented in tabular form together with approximate values of 04 A/Ok~.
Values of the spin-splitting factor g can in principle be derived from the observed absolute amplitudes of the de Haas-van Alphen oscillations, provided the oscillations are not dominated by magnetic interaction, and it is shown that this can be achieved for the bellies of the noble metals by working at sufficiently high temperatures (typically 2-3 K atfields up to 8 T). Oscillations were observed by the field modulation technique and g values obtained forCu, Au, and Ag over a range of orientations. The results are compared with previous ones for Cu and Au and it is also shown that the general trend from one metal to the other is roughly in accord with the predictions of many-body theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
