Abstract

The de Haas-van Alphen (dHvA) effect of the stage-1 compound intercalated with CdCl2 has been investigated with magnetic fields up to 14 T and for temperatures between 50 mK and 1.87 K. There are two dominant oscillations with values of 1144 and 1190 T with the magnetic field parallel to the c axis. The average value of the mass for these two frequencies is (0.26±0.01)m0, where m0 is the mass of the electron. The change of the frequencies with magnetic-field direction shows that the Fermi surface is an undulating cylinder directed along the c axis with a 4% difference between the minimum and maximum cross-sectional areas. The Fermi energy determined from the Holzwarth band model is -1.113 eV. There is also a dHvA frequency of 334 T with the magnetic field parallel to the c axis from a minority carrier.
