Abstract

In order to examine the quadrupolar effect in heavy rare-earth compounds HoB₆ and DyB₆, we have measured the elastic constants in magnetic fields by the ultrasonic method. The transverse C₄₄ mode of both compounds exhibits huge softening following as C₄₄ = C₄₄⁰(T-T_c⁰)/(T-Θ) above the ferro-quadrupolar transition temperature T_Q = 30.2 K for DyB₆ and T_Q = 6.1 K for HoB₆. The X-ray measurement of the lattice constant of DyB₆ and the magnetic field dependence of C₄₄ in both compounds are also discussed.
