Résumé : Monte Carlo estimates of the heat capacity of the two-dimensional O(n) spin systems with n=3, 4 and 5 are compared to the results given by the spherical model (n to infinity ). The values of the maxima of the heat capacity are approximately equal to 1/2n, when the temperature is 2n-1. The C/n against nT curves of the estimates come close to the curve of the spherical model for nT>or approximately=4.
