Peculiarities of optical absorption spectra of NdFe(BO) crystal in magnetically ordered state and at the transition to spiral magnetic phase
V. V. Slavin, I. S. Kachur, V. S. Kurnosov +1
We study experimentally and theoretically optical absorption spectra of neodymium ferroborate in the temperature range K. We show that the temperature dependences of integra…
Non-Abelian statistics in light scattering processes across interacting Haldane chains
Vladimir Gnezdilov, Vladimir Kurnosov, Yurii Pashkevich +6
The Haldane state is constructed from a product of local singlet dimers in the bulk and topological states at the edges of a chain. It is a fundamental representative of topo…
Flat-band spin dynamics and phonon anomalies of the saw-tooth spin-chain system FeO(SeO)
V. P. Gnezdilov, Yu. G. Pashkevich, V. S. Kurnosov +11
Fe ions form saw-tooth like chains along the axis of the oxo-selenite FeO(SeO) and an onset of long-range magnetic order is observed for temperatur…
Longitudinal magnon, inversion breaking and magnetic instabilities in the pseudo-Kagome francisites Cu3Bi(SeO3)2O2X with X=Br, Cl
V. Gnezdilov, Yu. Pashkevich, V. Kurnosov +6
We performed Raman studies and a dielectric characterization of the pseudo-kagome Cu3Bi(SeO3)2O2X (X = Cl, Br). These compounds share competing nearest-neighbour ferromagnetic exch…
