In this paper, we give some new definitions of compatible mappings in intuitionistic fuzzy metric spaces and we prove a common fixed point theorem for four mappings under the condition of compatible mappings of type $(I)$ and of type $(II)$ in complete intuitionistic fuzzy metric spaces.
Keywords: intuitionistic fuzzy metric space, common fixed point, compatible mappings and compatible mappings of types $(\alpha )$, $(\beta )$, $(I)$ and $(II)$
