  The modified Arrott plots and Kouvel${\text -}$Fisher analysis are used to
investigate the critical behavior of $CrTe_{1-x}Sb_{x}$ ferromagnetic material
near its transition temperature $T_{c}$. The Ferro${\text -}$Paramagnetic
transition is found to be a second${\text -}$order phase transition. For
$x=0.2$, the critical exponents closely follow the Mean Field Model with the
estimated values of the exponents: $\beta$ =0.60 $\pm$ 0.03, $\gamma$ =1.00
$\pm$ 0.03 and $\delta$ =2.67 $\pm$ 0.03. We also found with increasing
Sb${\text -}$concentrations, the critical exponents significantly deviate from
the mean field values and gradually shift towards the 3${\text -}$Dimensional
behavior. The deviation may indicate changes in the spin configuration with
increasing Sb concentrations.
