摘要：

We report measurements of the de Haas-van Alphen effect in CeIn3 in magnetic fields extending to approximate to 90 T, well above the Neel critical field of mu H-0(c) approximate to 61 T. The unreconstructed Fermi surface a sheet is observed in the high magnetic field polarized paramagnetic limit, but with its effective mass and Fermi surface volume strongly reduced in size compared to that observed in the low magnetic field paramagnetic regime under pressure. The spheroidal topology of this sheet provides an ideal realization of the transformation from a "large Fermi surface" accommodating f electrons to a "small Fermi surface" when the f-electron moments become polarized.
