Magnetic order in most materials occurs when magnetic ions with finite moments arrange in
a particular pattern below the ordering temperature. Intriguingly, if the crystal electric field …

The nature of an electric ferroaxial moment characterizing a time-reversal-even axial-vector
quantity is theoretically investigated under magnetic orderings. We clarify that a vortex spin …

Magnetization reversal in ferro-and ferrimagnets is a well-known archetype of non-
equilibrium processes, where the volume fractions of the oppositely magnetized domains …

Polar magnet Ni 3 TeO 6 has been recently attracting considerable interest due to its
nonhysteretic magnetoelectricity associated with the collinear antiferromagnetic (AFM) …

The polar antiferromagnet Co 2 Mo 3 O 8 was recently reported as a new multiferroic
material exhibiting remarkable second-order magnetoelectric (ME) coupling effect while no …

Discovering ferroic phase transitions and their consequential physical properties is at the
core of condensed matter science due to rich physics and tremendous technological …

The three-dimensional antiferromagnet Cu 3 TeO 6 has recently drawn significant attention
due to the coexistence of Dirac and triply degenerated magnons. Herein, we report that Cu 3 …

The magnetization and electric polarization of a polar antiferromagnet Fe 2 Mo 3 O 8 are
studied up to 66 T for spin-saturation magnetic fields applied along the polar axis. The …

The synchronized observation of a quantum magnetization plateau and multiferroicity is of
particular interest in frustrated antiferromagnets, but the modulation of two different …

We combined optical spectroscopy and first-principles electronic structure calculations to
reveal the charge gap in the polar magnet Fe 2 Mo 3 O 8. Iron occupation on the octahedral …
