Superconducting properties of new heavy fermion superconductor Ce2CoIn8

We have performed low-temperature specific heat and electrical resistivity measurements on a single-crystalline Ce2CoIn8. We observed a distinct jump at 0.47 K in specific heat, providing clear evidence of bulk superconductivity. H-c2(0) is 1.1 T for Hparallel toa and 0.9 T for Hparallel toc, respectively. The unknown steps observed resistivity, T-a1 and T-a2, shifted to low-temperature with increasing field and exhibits large anisotropy by field directions. (C) 2003 Elsevier B.V. All rights reserved.
