De Haas-van Alphen effect in CeB6 in fields up to 52T: Reduction of the cyclotron mass and new frequencies

Abstract The de Haas-van Alphen effect is used to study CeB 6 in pulsed fields up to 52 T. Two cyclotron orbits are observed; a previously unreported orbit may be due to magnetic breakdown. The cyclotron masses corresponding to these orbits decrease with increasing field.
