At 0 K the normal metal has a sharp Fermi surface, which is experimentally supported by the fact that the heat capacity is linear in the temperature T at the lowest temperatures. The Fermi surfaces in a few metals are discussed in this chapter.

Abstract Based on an itinerant model for the 4f electrons, the energy band structure is calculated for CeSn3, known to be the heavy-electron system having the Kondo temperature of about 200 K, by a self-consistent relativistic APW method with the exchange and correlation potential in the local-density approximation.

AbstractA study of the Shubnikov‐de Haas effect allowed us to determine the Fermi surface of tellurium. At low impurity concentration, the Fermi surfaces are ellipsoidal. When the impurity concentration increases, the ellipsoids coalesce and form a dumb‐bell surface. For p ≈ 1.5 × 1017 cm−3, the ellipsoids are just joining together.

Abstract A comparison of the Fermi surface calculated by a relativistic APW method and the local-density approximation with the de Haas-van Alphen effect observed in the heavy-electron system CeRu 2 Si 2 shows that the 4f electrons may not be itinerant in its ground state.

Recent magnetoreflection measurements in pyrolytic graphite have been interpreted using the magnetic energy levels obtained from the McClure-lnoue secular equation and the appropriate selection rules for interband transitions. Combining these results with those of the de Haas - van Alphen effect, the band parameters of the Slonczewski-Weiss model have ...

The Fermi surface of aluminium
Physics Letters, 1963Abstract The de Haas–van Alphen data in aluminium are compared with periods arising from extremal sections on a Fermi surface defined by a fourth-order secular equation. The Fourier coefficients V 111 and V 200 of the weak pseudopotential are regarded as adjustable parameters.

The Fermi surface of beryllium
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1963The Fermi surface of beryllium has been determined experimentally by studying the de Haas–van Alphen effect of single crystals in pulsed magnetic fields. The de Haas–van Alphen frequency (proportional to the extremal area of the Fermi surface normal to the field) was measured as a function of field direction.

The energy band structure of ferromagnetic nickel is evaluated by the Green's function method and the interpolation method developed by Slater and Koster. The effective potential is suitably chosen so as to give a reasonable fit with the results of recent experiments about the Fermi surface.
