Abstract We have measured the magnetoresistance and the de Haas-van Alphen (dHvA) effect in CeSn 3 . The magnetoresistance increases in all field directions. This result claims that CeSn 3 is a compensated metal. Compared to an uncompensated metal LaSn 3 , the 4f electrons in CeSn 3 become itinerant electrons.

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.

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 ...

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.

The low-frequency field modulation technique has been employed to study the de Haas-van Alphen effect in single crystals of niobium in fields up to 10 tesla. The frequency determination of the oscillations was performed by computer-based Fourier analysis and gave five sets of frequencies, which were studied in {100} and {110} planes.

The Fermi surfaces of copper, silver and gold. II. Calculation of the Fermi surfaces
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1962Fermi surfaces, similar in shape to that proposed for copper by Pippard, have been computed which fit Shoenberg’s experimental measurements of the de Haas-van Alphen effect in copper, silver and gold. It is shown that these are reasonably consistent with other experimental results, particularly the anomalous skin measurements of Pippard and Morton ...

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.
