Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet $T b_{2 + δ} T i_{2 - δ} O_{7}$

Y. Nii, Y. Hirokane, S. Nakamura +4

Electric quadrupolar state in a frustrated quantum magnet $T b_{2 + δ} T i_{2 - δ} O_{7}$ has been studied by means of ultrasonic and magnetostriction measurements. A single crys…

Electric Quadrupolar Contributions in the Magnetic Phases of UNi $_{4}$ B

T. Yanagisawa, H. Matsumori, H. Saito +10

We present acoustic signatures of the electric quadrupolar degrees of freedom in the honeycomb-layer compound UNi $_{4}$ B. The transverse ultrasonic mode $C_{66}$ shows softening belo…

Fermi surface in the absence of a Fermi liquid in the Kondo insulator SmB $_{6}$

M. Hartstein, W. H. Toews, Y. -T. Hsu +23

The search for a Fermi surface in the absence of a conventional Fermi liquid has thus far yielded very few potential candidates. Among promising materials are spin-frustrated Mott…

Observation of a new field-induced phase transition and its concomitant quantum critical fluctuations in CeCo(In $_{1 - x}$ Zn $_{x}$ ) $_{5}$

M. Yokoyama, H. Mashiko, R. Otaka +10

We demonstrate a close connection between observed field-induced antiferromagnetic (AFM) order and quantum critical fluctuation (QCF) in the Zn7%-doped heavy-fermion superconductor…

Control of ferroelectric phase by chemical pressure in (Gd,Tb)MnO $_{3}$ crystals

K. Noda, S. Nakamura, H. Kuwahara

We have investigated the dielectric properties of Gd $_{1 - x}$ Tb $_{x}$ MnO $_{3}$ crystals in magnetic fields to clarify the crossover between two distinct ferroelectric phases, GdMnO$…

Magnetic-Field and External-Pressure Control of Ferroelectricity in Multiferroic Manganites

H. Kuwahara, K. Noda, J. Nagayama +1

We have investigated dielectric properties in a series of crystals of $R$ MnO $_{3}$ ( $R$ is a rare earth ion) under magnetic fields and quasihydrostatic pressure. We have found that…

Magnetic-Field and External-Pressure Effect on Ferroelectricity in Manganites: Comparison between GdMnO $_{3}$ and TbMnO $_{3}$

K. Noda, S. Nakamura, J. Nagayama +1

We have investigated dielectric properties in Mott insulators GdMnO $_{3}$ and TbMnO $_{3}$ under magnetic fields and external quasihydrostatic pressures. In the case of GdMnO $_{3}$ ,…
