N2 - We have studied the entropy of two-dimensional t-J model by high temperature expansions through 14th order in inverse temperature. We extrapolated the series of entropy as a function of internal energy down to T = 0 and found that the entropy has wavy form in low doped case. We conclude that this indicate the spin-charge separation.
