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…
