Possible helimagnetic order in Co4+-containing perovskites Sr1-xCaxCoO3
Hidefumi Takahashi, Masaho Onose, Yasuhito Kobayashi +7
We systematically synthesized perovskite-type oxides Sr1-xCaxCoO3 containing unusually high valence Co4+ ions by a high pressure technique, and investigated the effect of systemati…
Higher order exchange driven noncoplanar magnetic state and large anomalous Hall effects in electron doped kagome magnet MnSn
Charanpreet Singh, Sk Jamaluddin, Ashis K. Nandy +3
Owing to the geometrical frustration, MnSn exhibits a 120 in-plane triangular antiferromagnetic (AFM) order with a large anomalous Hall effect (AHE). Here, we presen…
High-Field Ultrasonic Study of CeIrIn
Ryosuke Kurihara, Atsushi Miyake, Ryoma Tsunoda +3
We performed ultrasonic and temperature measurements under pulsed magnetic fields on CeIrIn to investigate whether or not the origin of metamagnetic transition and field-induce…
Field-tunable Weyl points and large anomalous Hall effects in degenerate magnetic semiconductor EuMgBi
M. Kondo, M. Ochi, R. Kurihara +10
Magnets, with topologically-nontrivial Dirac/Weyl points, have recently attracted significant attention owing to the unconventional physical properties, such as large anomalous Hal…
Spin-orbit-derived giant magnetoresistance in a layered magnetic semiconductor AgCrSe2
Hidefumi Takahashi, Tomoki Akiba, Alex Hiro Mayo +6
Two-dimensional magnetic materials have recently attracted great interest due to their unique functions as the electric field control of a magnetic phase and the anomalous spin Hal…
Highly anisotropic geometrical Hall effect via f-d exchange fields in doped pyrochlore molybdates
Hikaru Fukuda, Kentaro Ueda, Yoshio Kaneko +6
When a conduction electron couples with a non-coplanar localized magnetic moment, the realspace Berry curvature is exerted to cause the geometrical Hall effect, which is not simply…
Ferroelectric transition of a chiral molecular crystal BINOL2DMSO
Toshihiro Nomura, Takeshi Yajima, Zhuo Yang +7
We report dielectric, thermodynamical, acoustic, and optical properties of a chiral molecular crystal, 1,1'-bi-2-naphthol 2-dimethylsulfoxide (BINOL2DMSO). We find two successive p…
Magnetovolume Effect on the First-Order Metamagnetic Transition in UTe
Atsushi Miyake, Masaki Gen, Akihiko Ikeda +10
The link between the metamagnetic transition and novel spin-triplet superconductivity of UTe was discussed thermodynamically through magnetostriction measurements in a pulsed-m…
Magnetism of AlFeGeO with Andalusite Structure
K. Kakimoto, S. Takada, H. Ohta +8
The magnetism of AlFeGeO from = 0.09 to = 0.91 with andalusite structure was examined. The magnetic properties of AlFeGeO at low temperature…
Elastic Soft Mode and Electric Quadrupole Response in Excitonic Insulator Candidate (TaV)NiSe: Contribution of Electron-Phonon Interaction
Ryosuke Kurihara, Yusuke Hirose, Sumika Sano +4
We performed ultrasonic measurements on (TaV)NiSe to investigate the contribution of acoustic phonons at the zone center to structural and possible exci…
