Soft magnon contributions to dielectric constant in spiral magnets with domain walls
Francesco Foggetti, Sergey Artyukhin
Competing magnetic exchange interactions often result in non-collinear magnetic states, such as spin spirals, which break the inversion symmetry and induce ferroelectric polarizati…
Magnetic monopoles and toroidal moments in LuFeO and related compounds
Francesco Foggetti, Sang-Wook Cheong, Sergey Artyukhin
Magnetic monopoles and toroidal order are compelling features that have long been theorized but remain elusive in real materials. Multiferroic hexagonal ferrites are an interesting…
Dimerization-Induced Cross-Layer Quasi-Two-Dimensionality in Metallic Iridate IrTe2
G. L. Pascut, K. Haule, M. J. Gutmann +7
The crystal structure of layered metal IrTe2 is determined using single-crystal x-ray diffraction. At T=220 K, it exhibits Ir and Te dimers forming a valence-bond crystal. Electron…
Landau theory of topological defects in multiferroic hexagonal manganites
Sergey Artyukhin, Kris T. Delaney, Nicola A. Spaldin +1
Topological defects in ordered states with spontaneously broken symmetry often have unusual physical properties, such as fractional electric charge or a quantised magnetic field-fl…
Solitonic lattice and Yukawa forces in the rare earth orthoferrite TbFeO3
Sergey Artyukhin, Maxim Mostovoy, Niels Paduraru Jensen +13
The control of domains in ferroic devices lies at the heart of their potential for technological applications. Multiferroic materials offer another level of complexity as domains c…
Magnetic excitations in the low-temperature ferroelectric phase of multiferroic YMn2O5 using inelastic neutron scattering
J. -H. Kim, M. A. van. der. Vegte, A. Scaramucci +6
We studied magnetic excitations in a low-temperature ferroelectric phase of the multiferroic YMn2O5 using inelastic neutron scattering (INS). We identify low-energy magnon modes an…
