New Ce heavy-fermion system: CeCu/sub 6/

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)
We have discovered a new heavy-fermion system, CeCu/sub 6/, with a large susceptibility (chi = 0.027 emu/mole G at 1.5 K) and a large, temperature-dependent specific heat ..gamma.. below 10 K that is 840 mJ/mole K/sup 2/ at 1.8 K and extrapolates to 1.6 J/mole K/sup 2/ at T = 0 in analogy with CeAl/sub 3/. High-field specific-heat measurements agree almost perfectly with a narrow-band picture first proposed for UBe/sub 13/.
