Rare-earth hexaboride HoB6 shows a ferroquadrupole ordering of Oyz, Ozx and Oxy with ΓQ symmetry at TQ = 6.1 K accompanied by a structural change from cubic to trigonal. In order to examine the order parameter in HoB6, we have performed ultrasonic and thermal expansion measurements. The lattice length along [001] expands ΔL/L[001] = 2.5 × 10-4 just below TQ, while the length along [111] shrinks appreciably ΔL/L[111] = -4.5 × 10-3. This result confirms the cubic-trigonal distortion observed by neutron scattering experiments.
