We carried out a comprehensive study of magnetic critical behavior in single crystals of ternary chalcogenide that undergoes a ferrimagnetic transition below 123 K. Detailed critical behavior analysis and scaled magnetic entropy change indicate a second-order ferrimagnetic transition. Critical exponents with with , and at suggest that the spins approach the three-dimensional Ising ( , and ) model coupled with attractive long-range interactions between spins that decay as . Our results suggest that the ferrimagnetism in is due to itinerant ferromagnetism among the antiferromagnetically coupled Cr-Fe-Cr trimers.
