 Low-temperature calorimetry and resistivity of CeAl3

The 1975 measurements of CeAl3 below $0.2\mathrm{K}$ found an electronic heat capacity coefficient of $1.62\mathrm{J}\mathrm{mo}{\mathrm{l}}^{-1}{\mathrm{K}}^{-2}$ and a quadratic electrical-resistivity coefficient of $35\mu \mathrm{\Omega }\mathrm{cm}{\mathrm{K}}^{-2}$. These are complementary thermal and transport signatures of an unusually dense low-energy electronic spectrum.^[ref] A temperature sweep and a $C/T$ versus $T^2$ fit separate the electronic intercept from a Debye lattice term; the transport comparison tests a Fermi liquid temperature law.
