Abstract
We report on high-resolution acoustic, specific heat and thermal expansion measurements in the vicinity of the antiferromagnetic phase transition at T N = 1.88 K on a high-quality single crystal of the natural mineral azurite. A detailed investigation of the critical contribution to the various quantities at T N is presented. The set of critical exponents and amplitude ratios of the singular contributions above and below the transition indicate that the system can be reasonably well described by a three-dimensional Heisenberg antiferromagnet.

Similar behavior was also observed for ferroelectric phase transitions where the roll-off in the critical behavior was assigned to a strong piezoelectric coupling. For a review, see: T. Nattermann, Ferroelectrics 29, 75 (1980).
