Abstract
Thermal conductivity of a holmium single crystal has been measured in the temperature range 0.6 to 4.2°K. Around 1°K there is a total enhancement of over 30% in the conductivity value and the Lorenz number increases sharply to beyond 3.8 × W Ω. When correlated with specific heat data, this extra contribution appears to be a nuclear hyperfine effect. A possible mechanism is proposed.
