Magnetic frustration in a material may drive spin-spiral order, spontaneously breaking the translation and chiral symmetries of crystal. The underlying hierarchy magnetic interactions is reflected magnon excitations, which can be probed by inelastic neutron scattering. Here, authors study dispersions magnons helimagnet FeP compare experimentally observed spectra with simulations. Upon examination alternative models, are able to correctly describe spin excitations unveil corresponding mechanism.
The spiral spin liquid (SSL) is a highly degenerate state characterized by continuous contour or surface in reciprocal space spanned propagation vector. Although the SSL has been predicted number of various theoretical models, very few materials are so far experimentally identified to host such state. Via combined single-crystal wide-angle and small-angle neutron scattering, we report observation quasi-two-dimensional delafossite AgCrSe$_2$. We show that it close realization ideal Heisenberg...
The development of novel membrane materials for hydrogen fuel cells, a promising environmentally friendly technology, represents relevant research task. In this work, we propose an approach to creating proton-conducting membranes from industrial polyethylene terephthalate (PET) dielectric track-etched film. An N, P-containing ionic liquid was used as modifying agent, whose polymerization carried out directly in the PET pores. obtained using directed synthesis organophosphorus compounds...
Multiple intriguing phenomena have recently been discovered in tetragonal Heusler compounds, where $D_{2d}$ symmetry sets a unique interplay between Dzyaloshinskii-Moriya (DM) and magnetic dipolar interactions. In the prototype compound Mn$_{1.4}$PtSn, this has allowed stabilization of exotic spin textures such as first-reported anti-skyrmions or elliptic Bloch-type skyrmions. While less attention so far given to low-field spiral state, remains extremely interesting simplest phase scenario...
