Acoustic Signatures of the Phases and Phase Transitions in the Blume Capel Model with Random Crystal Field
Sound propagation in the Blume Capel model with quenched diluted single-ion anisotropy is investigated. The sound dispersion relation and an expression for the ultrasonic attenuation are derived with the aid of the method of thermodynamics of irreversible processes. A frequency-dependent dispersion...
