De Haas-van Alphen effect in LuAl3

We have measured the de Haas-van Alphen (dHvA) effect in LuAl3 at temperatures between 1.3 K and 4.2 K in magnetic fields up to 13 T. Observed frequencies range from 400 T to 23 kT. The highest one corresponds to a cyclotron orbit with an area equal to a square face of the Brillouin zone. The angular dependence of the frequencies suggests that the Fermi surfaces are composed of a nearly spherical closed sheet and multiple connected open sheet. The observed cyclotron effective masses for the closed Fermi surface are about 0.7 and those for open Fermi surface range from 0.3 to 1 in units of the free electron mass. A band structure calculation was carried out by a full potential linearized APW method. The gross feature of the observed results was explained by the calculation. (C) 2001 Elsevier Science B.V.
