Thermal transport of single-crystal HoNi2B2C and DyNi2B2C Conference Paper uri icon

abstract

  • The quaternary intermetallic rare-earth nickel borocarbides, RNi2B2C, are a family of compounds that show magnetic behavior, superconducting behavior, and/or both. Thermal transport measurements reveal both electron and phonon scattering mechanisms, and can provide information on the interplay of these two long-range phenomena. For R = Dy and Ho, the thermal conductivity is dominated by electrons and the low temperature thermal conductivity exhibits a marked loss of scattering at the antiferromagnetic ordering temperature, TN. Unlike the case for R = Y and Lu non-magnetic superconductors, a phonon peak in the thermal conductivity below Tc is not observed down to T = 1.4 K for the R = Dy and Ho magnetic superconductors. 2001 Elsevier Science B.V.
