Abstract
The critical exponents gamma (c) = 0.84(7) of the chiral susceptibility above the Neel temperature, T-N, and beta (c) = 0.44(2) of the average chirality below T-N have been determined for the triangular-lattice antiferromagnet CsMnBr3 by means of polarized neutron scattering. These first experimental values of chiral critical exponents are in line with theoretical predictions and fulfill their scaling relation. The temperature at which the average chirality appears coincides with the spin-order transition temperature, T-N.
