Abstract
Measurements of the de Haas-van Alphen effect in the normal state of the he avy-fermion superconductor CeCoIn5 have been carried out using a torque can tilever at temperatures ranging from 20 to 500 mK and in fields up to 18 T. Angular-dependent measurements of the extremal Fermi surface areas reveal a more extreme two-dimensional sheet than is found in either CeRhIn5 or CeI rIn5. The effective masses of the measured frequencies range from 9 to 20m* /m(0).
