We have discovered a new heavy-fermion system, CeCu6, with a large susceptibility (=0.027 emu/mole G at 1.5 K) and a large, temperature-dependent specific heat below 10 K that is 840 mJ/mole K2 at 1.8 K and extrapolates to 1.6 J/mole K2 at T=0 in analogy with CeAl3. High-field specific-heat measurements agree almost perfectly with a narrow-band picture first proposed for UBe13. © 1984 The American Physical Society.
