EPR studies of the triangular-lattice antiferromagnet Cs₂CuBr₄
The spin dynamics of the spin-1/2 triangular-lattice antiferromagnet Cs₂CuBr₄ is probed by means of high-frequency electron paramagnetic resonance (EPR) spectroscopy. Temperature dependences of EPR parameters are studied in a broad temperature range between 1.4 and 200 K for different orientations o...

| description | The spin dynamics of the spin-1/2 triangular-lattice antiferromagnet Cs₂CuBr₄ is probed by means of high-frequency electron paramagnetic resonance (EPR) spectroscopy. Temperature dependences of EPR parameters are studied in a broad temperature range between 1.4 and 200 K for different orientations of the applied magnetic field. In the high-temperature regime (T >> J/kB), an unusually broad and anisotropic resonance line is detected, suggesting a sizeable Dzyaloshinskii–Moriya interaction. Employing the theory of exchange narrowing, the ratio of the Dzyaloshinskii–Moriya vector components, Dc/Da ≈ 0.3, is estimated.
