Mott insulators with strong spin-orbit coupling have been proposed to host unconventional
magnetic states, including the Kitaev quantum spin liquid. The 4 d system α-RuCl 3 has …

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 …

Parity-odd magnetoelectric multipoles such as magnetic quadrupoles and toroidal dipoles
contribute to various symmetry-dependent magnetic phenomena and formation of exotic …

In this paper, a novel mixed Tutton salt (NH 4) 2 Mn 0. 47 Cu 0. 53 (SO 4) 2 (H 2 O) 6
obtained in single crystal form is described. Their structural, thermal, electrical, and …

EPR parameters and the local configurations of the transition metal (TM) ions VO 2+ and Cu
2+ in BaO-TeO 2-B 2 O 3 glasses were experimentally evaluated and also theoretically …

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 …

The study of chemical factors that influence pigment coloring is a field of fundamental
interest that is still dominated by many uncertainties. In this Article, we investigate, by means …

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

We demonstrate mechanisms of reciprocity breaking in nonlinear optics driven by the
toroidal dipole moment which characterizes nontrivial spatial distributions of spins in solids …

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 …
