Abstract

Ultrasonic measurements of the soft-mode elastic constant 1/2 (C11 - C12) have been performed to investigate the pseudospin susceptibility of the random-field system Dy (AsxV1-x) O4. The susceptibility critical exponent γ = 1.73 ± 0.07 for x = 0.17 is much larger than for the pure compound (x = 0), in reasonable agreement with predictions of the random-field Ising model.
