MoPSiO: a honeycomb antiferromagnet with disconnected octahedra
Danis I. Badrtdinov, Lei Ding, Clemens Ritter +4
We report the crystal structure and magnetic behavior of the spin- silicophosphate MoPSiO studied by high-resolution synchrotron x-ray diffraction, neutr…
Field-tunable toroidal moment in a chiral-lattice magnet
Lei Ding, Xianghan Xu, Harald O. Jeschke +13
A toroidal dipole moment appears independent of the electric and magnetic dipole moment in the multipole expansion of electrodynamics. It arises naturally from vortex-like arrangem…
Neutron diffraction study of magnetism in van der Waals layered MnBiTe
