Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet
Y. Nii, Y. Hirokane, S. Nakamura +4
Electric quadrupolar state in a frustrated quantum magnet has been studied by means of ultrasonic and magnetostriction measurements. A single crys…
Electric Quadrupolar Contributions in the Magnetic Phases of UNiB
T. Yanagisawa, H. Matsumori, H. Saito +10
We present acoustic signatures of the electric quadrupolar degrees of freedom in the honeycomb-layer compound UNiB. The transverse ultrasonic mode shows softening belo…
Fermi surface in the absence of a Fermi liquid in the Kondo insulator SmB
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(InZn)
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…
Magnetic field-induced insulator-semimetal transition in a pyrochlore Nd2Ir2O7
K. Ueda, J. Fujioka, B. -J. Yang +6
We have investigated magneto-transport properties in a single crystal of pyrochore-type Nd2Ir2O7. The metallic conduction is observed on the antiferromagnetic domain walls of the a…
New Heat-Capacity Measurements of the Possible Order-Disorder Transition in the 4/7-phase of 2D Helium
S. Nakamura, K. Matsui, T. Matsui +1
We have developed a new heat-capacity measuring system with ZYX graphite that is known to have much better crystallinity than Grafoil and started data collection. We report prelimi…
