Search for Multipolar Instability in URu$_2$Si$_2$ Studied by Ultrasonic Measurements under Pulsed Magnetic Field

Autor: Yanagisawa, T., Mombetsu, S., Hidaka, H., Amitsuka, H., Cong, P. T., Yasin, S., Zherlitsyn, S., Wosnitza, J., Huang, K., Kanchanavatee, N., Janoschek, M., Maple, M. B., Aoki, D.

The elastic properties of URu$_2$Si$_2$ in the high-magnetic field region above 40 T, over a wide temperature range from 1.5 to 120 K, were systematically investigated by means of high-frequency ultrasonic measurements. The investigation was performe

Study of Localized Character of 4f Electrons and Ultrasonic Dispersions in SmOs4Sb12 by High-Pressure High-Frequency Ultrasonic Measurements

Autor: Mombetsu, S., Murazumi, T., Hidaka, H., Yanagisawa, T., Amitsuka, H., Ho, P. -C., Maple, M. B.

Publikováno v: Phys. Rev. B 94, 085142 (2016)

We present high-frequency ultrasonic measurements on the filled skutterudite SmOs$_4$Sb$_{12}$ under hydrostatic pressure. The results clarify that the 4$f$ electrons in this compound transform from delocalized at ambient pressure to localized at hig

Changes in elastic moduli as evidence for quadrupolar ordering in the rare-earth frustrated magnet Tb2Ti2O7

Autor: Gritsenko, Y., Mombetsu, S., Cong, P. T., Stöter, T., Green, E. L., Salazar Mejia, C., Wosnitza, J., Ruminy, M., Fennell, T., Zvyagin, A. A., Zherlitsyn, S., Kenzelmann, M.

Publikováno v: Physical Review B 102(2020), 060403(R)

Numerous materials feature unexplained phases with invisible or hidden order of electronic origin. A particularly mysterious case is that of Tb2Ti2O7, which avoids magnetic order to the lowest temperatures, but nevertheless has an unexplained second-

Crystalline Electric Field and Kondo Effect in SmOs4Sb12

Autor: Mombetsu, S., Yanagisawa, T., Hidaka, H., Amitsuka, H., Yasin, S., Zherlitsyn, S., Wosnitza, J., Ho, P.-C., Maple, M. B.

Journal of the Physical Society of Japan 85(2016), 043704

Our ultrasound results obtained in pulsed magnetic fields show that the filled-skutterudite compound SmOs4Sb12 has the Γ67 quartet crystalline-electric-field ground state. This fact suggests that the multipolar degrees of freedom of the Γ quartet p
