　　We have investigated the critical behavior near the ferromagnetic transition of T1Co2S2 single crystals and the magnetic properties of Tl(Co0.95Ni0.05)2S2 by means of magnetization measurements.The critical exponents β, γ, σ obtained could basically satisfy the scaling equations and are very close to the prediction of a tricritical point (TCP).
