在20 ~ 500 mK温度范围内，在18 T磁场下，用悬臂梁测量了重费米子超导体CeCoIn_5正常态的de Haas-van Alphen效应。依赖于角度的测量的极值费米表面积揭示了一个更极端的二维片比发现在CeRhIn 5或CeIrIn 5。测量频率的有效质量范围为9 ~ 20 m */m（0）。
Measurements of the de Haas-van Alphen effect in the normal state of the heavy-fermion superconductor CeCoIn5 have been carried out using a torque cantilever 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 CeIrIn5. The effective masses of the measured frequencies range from 9 to 20m*/m(0).
