Recent studies on weak ferromagnets Fe2-xMnxCrAl (0<x<1) reveal the presenceof cluster glass (CG) and Griffiths phase (GP) below and above theferromagnetic transition temperature (TC) [(2019) Sci. Rep. 9 15888]. In thiswork, the influence of these inhomogeneous phases on the critical behaviour(around TC) of the above-mentioned series of alloys has been investigated indetail. For the parent alloy Fe2CrAl, {\gamma} is estimated as ~ 1.34, whichlies near to ordered 3D Heisenberg model, whereas obtained value of {\beta} ~0.273 does not belong to any universality class. With increment in Mnconcentration, both exponents {\gamma} and \b{eta} increases, where {\gamma}and {\beta} approaches disordered 3D Heisenberg model and ordered 3D Heisenbergmodel, respectively. The observed deviation in {\gamma} and unconventionalvalue of {\delta} can be ascribed to the increment in GP with Mn-concentration.The trend noted for {\beta} can be attributed to the increment in CG regimewith an increase in Mn-content. The self-consistency and reliability of theestimated exponents are verified by the Widom scaling relation and scalingequations of state. Our studies indicate that the critical phenomenon ofFe2-xMnxCrAl (0<x<1) alloys possibly belong to a separate class and is notdescribed within the framework of any existing universal model.
