Magneto-acoustic Quantum Oscillations and the Fermi Surface of UPt<sub>3</sub>

ORAL

Abstract

We report details of magneto-acoustic quantum oscillations measured for several different angles of the magnetic field away from the a-axis as well as the c-axis in UPt3 for temperatures down to 35 mK. The effective masses of the electrons in the observed orbits obtained from the temperature dependence of the amplitudes of the oscillations will be presented. The field dependence of the frequencies of the orbits will be discussed and the low field values will be compared with the known band structure predictions of UPt3.
