Antiferromagnetic resonance and two-magnon absorption in an XXZ-chain antiferromagnet Cs2CoCl4
T. A. Soldatov, A. I. Smirnov
Magnetic excitations of the exchange-dipole quasi 1D XXZ antiferromagnet are studied in the ordered phase. We observe a transformation of the electron spin resonance (ESR) spectrum…
Dynamics of anisotropic frustrated antiferromagnet Cs2CoBr4 in a spin-liquid regime
T. A. Soldatov, A. I. Smirnov, A. V. Syromyatnikov
Cs2CoBr4 is a triangular-lattice antiferromagnet which can be viewed as weakly interacting spin chains due to spatially anisotropic frustrating exchange couplings. The spin-orbit i…
Spin dynamics in ordered phases of anisotropic triangular-lattice antiferromagnet Cs2CoBr4
T. A. Soldatov, A. I. Smirnov, A. V. Syromyatnikov
We study spin dynamics of ordered phases of Cs2CoBr4 in a magnetic field using electron spin resonance (ESR) technique and theoretical analysis. This material hosts weakly interact…
Electron Spin Resonance of the Interacting Spinon Liquid
Kirill Yu. Povarov, Timofei A. Soldatov, Ren-Bo Wang +3
We report experimental verification of the recently predicted collective modes of spinons, stabilized by backscattering interaction, in a model quantum spin chain material. We expl…
Microwave dynamics of pure and doped anisotropic S=1 chain antiferromagnet NiCl2-4SC(NH2)2
T. A. Soldatov, A. I. Smirnov, K. Yu. Povarov +2
We studied electron spin resonance in a quantum magnet NiCl2-4SC(NH2)2, demonstrating a field-induced quantum phase transition from a quantum-disordered phase to an antiferromagnet…

T. A. Soldatov, A. I. Smirnov, K. Yu. Povarov +3
Electron spin resonance experiments in the quasi-1D S=1/2 antiferromagnet KCuSOCl reveal opening of a gap in absence of magnetic ordering, as well as an anisotropic shi…
Multiferroicity of CuCrO2 tested by ESR
S. K. Gotovko, T. A. Soldatov, L. E. Svistov +1
We have carried out the ESR study of the multiferroic triangular antiferromagnet CuCrO2 in the presence of an electric field. The shift of ESR spectra by the electric field was obs…
Experimental study of antiferromagnetic resonance in noncollinear antiferromagnet MnAlGeO
Yu. V. Krasnikova, V. N. Glazkov, T. A. Soldatov
We have measured antiferromagnetic resonance (AFMR) frequency-field dependences for aluminum-manganese garnet MnAlGeO at frequencies from 1 to 125 GHz and…
Order by quenched disorder in the model triangular antiferromagnet RbFe(MoO4)2
A. I. Smirnov, T. A. Soldatov, O. A. Petrenko +5
We observe a disappearance of the 1/3 magnetization plateau and a striking change of the magnetic configuration under a moderate doping of the model triangular antiferromagnet RbFe…
Electron spin resonance in a model S=1/2 chain antiferromagnet with a uniform Dzyaloshinskii--Moriya interaction

The electron spin resonance spectrum of a quasi 1D S=1/2 antiferromagnet K2CuSO4Br2 was found to demonstrate an energy gap and a doublet of resonance lines in a wide temperature ra…
