We have reported curious behavior found in the elastic constant associated with the Metal–Insulator (M–I) transition and the successive phase transition in SmRu 4 P 12 . To explain characteristic properties of SmRu 4 P 12 , we focus our attention

We have studied the origin of the successive phase transitions in filled skutterudite SmRu 4 P 12 based on the results of elastic constant measurements. The temperature dependence of the elastic constants shows a sharp drop at the metal–insulator (

We have investigated the magnetic properties of Ce x La 1- x Sb alloys for x =0.9 and 0.5 by means of magnetization and specific heat measurements. They exhibit the magnetic ordering below 11.4 K for x =0.9 and 1.5 K for x =0.5. Their distinct anomal

We performed numerical simulations on a two-dimensional inelastic hard disk system under gravity with a heat bath to study the dynamics of granular fluidization. Upon increasing the temperature of the heat bath, we found that three phases, namely, th

We investigated elastic properties of the filled skutterudite compound with heavy lanthanide TbRu 4 P 12 by means of ultrasonic measurements for the first time. TbRu 4 P 12 undergoes a two-successive phase transition from a paramagnetic to an antifer

The absence of back scattering in carbon nanotubes is shown to be ascribed to Berry's phase which corresponds to a sign change of the wave function under a spin rotation of a neutrino-like particle in a two-dimensional graphite. Effects of trigonal w

Compositional phase separation was observed in La 2- x Ba x CuO y near the optimum composition ( x ∼0.16) for superconductivity with a decisive miscibility gap by means of X-ray diffraction measurements. The phase-separated samples do not show intr

We present the experimental results of DC magnetization measurements on the bilayer manganese oxide (Pr 0.6 La 0.4 ) 1.2 Sr 1.8 Mn 2 O 7 under pressure. The data were taken to elucidate the magnetic properties of the field-induced ferromagnetic phase

Elastic constant measurements were performed for the filled skutterudite compound SmRu4P12 in a pulsed magnetic field up to 55 T of \(H\parallel\langle 111\rangle\) to create a high-field phase diagram. The field dependence of the transverse elastic
