The magnetic structure and magnetoelectric effect have been investigated for single crystals
of the antiferromagnet Co 4 Nb 2 O 9. Single-crystal neutron diffraction and magnetic …

The manipulation of magnetic ordering with applied electric fields is of pressing interest for
new magnetoelectric devices and information storage applications. Recently, such …

We experimentally demonstrate one-way transparency of light in multiferroic CuB 2 O 4. The
material is rendered transparent for light propagating in one direction, while opaque for light …

Honeycomb-based materials have been attracting a lot of attention owing to their fascinating
physics as exemplified by the emergence of a massless Dirac fermion and a spin liquid …

In magnetoelectric and multiferroic materials, the magnetic degree of freedom can be
controlled by electric field, and vice versa. A significant amount of research has been …

Mirror symmetries are of particular importance because they are connected to fundamental
properties and conservation laws. Spatial inversion and time reversal are typically …

Magnetic control of the crystal chirality was announced by Saito et al.[Phys. Rev. Lett. 101,
117402 (2008)] on the ground of experiments in Cu B 2 O 4. This claim has raised a sharp …

Violation of time reversal and spatial inversion symmetries has profound consequences for
