Abstract

The mean long-wavelength acoustic-mode Grüneisen parameter of a Cr + 0.84 at% Ga alloy single crystal is reported as a function of temperature. Magnetic effects in this crystal give rise to large mean vibrational anharmonicity of the acoustic phonons in the vicinity of the Néel transition.
