In filled skutterudite compounds and clathrate compounds, guest atoms, which are accommodated in polyhedral cages, exhibit an anharmonic oscillation so-called the rattling motion. The rattling motion is suggested by inelastic neutron scattering exper

We report the temperature dependence of the elastic modulus and the specific heat of CeRhIn. The elastic modulus softens and takes a minimum around 120 K. The magnetic contribution to the specific heat takes a broad maximum around 130 K. These result

The elastic moduli C44 and (C11‐C12)/2 have been measured for rare earth dodecaboride TmB12. With decreasing temperature, both moduli show characteristic softening due to a crystal electric field effect. We have determined a 4f‐electronic level s

The ternary uranium compound UCu$_2$Sn with a hexagonal ZrPt$_2$Al-type structure shows a phase transition at 16 K. We reported previously that huge lattice-softening is accompanied by the phase transition, which originates from ferroquadrupolar orde

We measured temperature dependence of elastic modulus for the high-quality single crystals of Y 1-x Ca x TiO 3 (x = 0,0.1 and 0.2) using an ultrasonic technique. A step like elastic anomaly due to the volume magnetostriction induced by a ferromagneti

We measured various elastic moduli of single-crystalline Y 1 - x Ca x TiO 3 ( x = 0 , and 0.2) as a function of temperature by means of an ultrasonic technique. Remarkable elastic softening has been found in transverse C 44 for the sample with x = 0
