N2 - Recently, magnetic substances with chirality, namely the handedness of the magnetic structure, have attracted considerable attention because of the anomalous phenomena which appear in magnetic fields. CrNb3S6 is one of the chiral magnets formed by exchange and Dzyaloshinsky-Moriya (DM) interactions. Electron spin resonance (ESR) measurements of CrNb3S6 in magnetic fields parallel to the c-axis (helical axis) have been performed to evaluate the exchange and the DM constants that determine the helical structure. Fitting the ESR data to a calculated mode based on a spin wave theory yields values for the ferromagnetic inter-plane exchange constant J/kB = 16.2 K, the DM constant D/kB = 1.29 K, and the single-ion anisotropy constant. From the Curie-Weiss temperature θCW ∼ 145 K, large intra-plane ferromagnetic exchange interactions are suggested.
