The search for new materials energy-efficient electronic devices has gained unprecedented importance. Among the various classes of magnetic driving this are antiferromagnets, magnetoelectrics, and systems with topological spin excitations. Cu_{3}TeO_{6} is a material that belongs to all three these classes. Combining static electric polarization torque measurements phenomenological simulations we demonstrate magnetic-field-induced reorientation needs be taken into account understand linear...
The search for and understanding of low-dimensional magnetic materials is essential both fundamental technological purposes. Here we propose a combined experimental theoretical investigation such system, namely the monoclinic phase ${\mathrm{SeCuO}}_{3}$. This spin-$\frac{1}{2}$ antiferromagnet appears to be based on two decoupled subsystems which respond differently applied field in antiferromagnetic phase. From our results are able zero-field structure as well more exotic finite structure,...
Vector-chiral (VC) antiferromagnetism is a spiral-like ordering of spins which may allow ferroelectricity to occur due loss space inversion symmetry. In this paper we report direct experimental observation in the VC phase $\beta$-TeVO$_4$, frustrated spin chain system with pronounced magnetic anisotropy and rich diagram. Saturation polarization proportional neutron scattering intensities that correspond reflection. This implies inverse Dzyaloshinskii-Moriya mechanism responsible for driving...
$\ensuremath{\beta}\text{\ensuremath{-}}{\mathrm{TeVO}}_{4}$ is a frustrated spin-1/2 zig-zag chain system, where spin-density-wave (SDW), vector-chiral (VC) and an exotic dynamic spin-stripe phase compete at low temperatures. Here we use torque magnetometry to study the anisotropy of these phases in magnetic fields up 5 T. Our results show that magnetic-field-induced spin reorientation occurs SDW for ${\ensuremath{\mu}}_{0}H\ensuremath{\ge}2$ The observed another element anisotropic diagram...
