Abstract
Precise measurements of the specific heat of CsMnF3 near its Neel temperature (TN) are reported. A detailed analysis of the critical singularity shows evidence for a crossover behaviour near TN. This observation is an experimental verification of the spin dimensionality crossover phenomenon from a three-dimensional Heisenberg-like behaviour far from TN to a three-dimensional XY-like behaviour in the near vicinity of TN.Keywords
