We carried out a comprehensive study of magnetic critical behavior in single crystals of ternary chalcogenide FeCr2Te4 that undergoes a ferrimagnetic transition below Tc~ 123 K. Detailed critical behavior analysis and scaled magnetic entropy change indicate a second-order ferrimagnetic transition. Critical exponents β=0.30(1) with Tc=122.4(5)K , γ=1.22(1) with Tc=122.8(1)K , and δ=4.24(2) at Tc~123K suggest that the spins approach the three-dimensional Ising ( β=0.325, γ=1.24 , and δ=4.82 ) model coupled with attractive long-range interactions between spins that decay as J(r)r-4.88 . Our results suggest that the ferrimagnetism in FeCr2Te4 is due to itinerant ferromagnetism among the antiferromagnetically coupled Cr-Fe-Cr trimers.
