Description
TmVO4 thermal conductivity is measured between 80 mK and 50 K for H = 0 and 70 kOe. It is found that a large phonon scattering is present at H = 0 compared to the H = 70 kOe measurement. Using a Mori-Zwanzig formalism, a theoretical analysis may explain the general behaviour in the temperature region below the phase transition temperature. (author)
