Observation of converse flexoelectric effect in topological semimetals
Hidefumi Takahashi, Yusuke Kurosaka, Kenta Kimura +2
A strong coupling between electric polarization and elastic deformation in solids is an important factor in creating useful electromechanical nanodevices. Such coupling is typicall…
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…
Magnetic Structural Unit with Convex Geometry: a Building Block Hosting an Exchange-striction-driven Magnetoelectric Coupling
Kenta Kimura, Yasuyuki Kato, Kunihiko Yamauchi +10
We perform a combined experimental and theoretical study of a magnetic-field () induced evolution of magnetic and ferroelectric properties in an antiferromagnetic material Pb(Ti…
-cation control of magnetoelectric quadrupole order in (TiO)Cu(PO) ( = Ba, Sr, and Pb)
K. Kimura, M. Toyoda, P. Babkevich +5
Ferroic magnetic quadrupole order exhibiting macroscopic magnetoelectric activity is discovered in the novel compound (TiO)Cu(PO) with = Pb, which is in contrast…
Crystal Field Excitations in Breathing Pyrochlore Antiferromagnet Ba3Yb2Zn5O11
T. Haku, M. Soda, M. Sera +4
Inelastic neutron scattering measurement is performed on a breathing pyrochlore antiferromagnet Ba3Yb2Zn5O11. The observed dispersionless excitations are explained by a crystalline…
Coupling of magnetic and ferroelectric hysteresis by a multi-component magnetic structure in Mn2GeO4
J. S. White, T. Honda, K. Kimura +6
The olivine compound Mn2GeO4 is shown to feature both a ferroelectric polarization and a ferromagnetic magnetization that are directly coupled and point along the same direction. W…
