摘要：

We report on measurements of the specific heat, C, of the triangular lattice antiferromagnet CsMnI3 in the vicinity of the two successive phase transitions at T(N1) = 11.28 K and T(N2) = 8.19 K and in magnetic fields up to 6 T applied perpendicular to the c axis. Near T(N2) the data can be fitted with a critical exponent alpha = -0.05 +/- 0.15 for B = 0 compatible with the prediction of three-dimensional ordering with XY symmetry for this transition. Within the experimental uncertainty, the critical behaviour is not affected by a magnetic field.
