note = "Funding Information: A De Haas-Van Alphen study of Pt shows that the whole of the Fermi surface is very similar to that for Pd. The s-band contains 0.40 electrons/atom. The galvanomagnetic data are interpreted in terms of a second d-band surface open along [loo], and we have observed the associated neck area of 7.36 x 10v2 a.u We have studied the De Haas-Van Alphen effect in Pt by a modulation technique in fields up to 53 kG and at temperatures of 0.92 to 2.OoK. The samples had resistivity ratios ranging from 35O(Pt o 4000. We find striking similarities to the Pd Fermi surface [l]. Recent experimental and theoretical work has shown that a rigid band model gives a good first approximation to the band structure of the other fee transition metals Pd [l, 21, Rh [3], nonmagnetic Ni [4] and the noble metals [5,6]***. All the experimental data can be interpreted using the Cu-band structure [5] with a change in Fermi level appropriate to the number of valence electrons. The recent De Haas-Van Alphen data for [{\textquoteleft}#{\textquoteleft}I show the presence of small ellipsoidal pockets which are interpreted as d-band holes at X, because of their similarity in both symmetry and anisotropy to those previously found in Pd. These are thus associated with the same X5 (or X6+ with spin) level as in Pd [ 1,2]. We observe in Pt two other groups of frequencies, both of which are associated with much * Supported by the National Science Foundation, the Advanced Research Projects Agency, and the Atomic Energy Commission. ** Present address: Royal Society Mond Laboratory, University of Cambridge, Cambridge, England. *** The calculated band structure for Cu has been con-firmed by numerous experiments.",
