High-field magnetic structure of the triangular antiferromagnet RbFe(MoO4)2
Yu. A. Sakhratov, O. Prokhnenko, A. Ya. Shapiro +4
The magnetic H - T phase diagram of a quasi-two-dimensional antiferromagnet RbFe(MoO4)2 with an equilateral triangular lattice structure is studied with 87Rb NMR and neutron diffra…
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…
High-field magnetic resonance of spinons and magnons in a triangular lattice S=1/2 antiferromagnet Cs2CuCl4
A. I. Smirnov, T. A. Soldatov, K. Yu. Povarov +1
The electron spin resonance doublet indicating the width of the two spinon continuum in a spin-1/2 triangular-lattice Heisenberg antiferromagnet Cs2CuCl4 was studied in high magnet…
Direct determination of exchange parameters in Cs2CuBr4 and Cs2CuCl4: high-field ESR studies
S. A. Zvyagin, D. Kamenskyi, M. Ozerov +12
Spin-1/2 Heisenberg antiferromagnets CsCuCl and CsCuBr with distorted triangular-lattice structures are studied by means of electron spin resonance spectroscopy in…
Magnetic resonance in the ordered phases of the 2D frustrated quantum magnet Cs2CuCl4
A. I. Smirnov, K. Yu. Povarov, S. V. Petrov +1
The temperature evolution of the electron spin resonance is studied at cooling the crystal samples of Cs2CuCl4 through the Neel point 0.62 K. A coexistence of the high-frequency sp…
Modes of magnetic resonance in the spin liquid phase of Cs2CuCl4
K. Yu. Povarov, A. I. Smirnov, O. A. Starykh +2
We report the observation of a frequency shift and splitting of the electron spin resonance (ESR) mode of the low-dimensional S=1/2 frustrated antiferromagnet Cs2CuCl4 in the spin-…
