We examine the magnetic properties of the quasi 2D ferrimagnetic singlecrystal Mn3Si2Te6 (MST) through critical phenomena and magnetic entropyanalysis in the easy axis (H || ab) as a function of proton irradiance.Employing a modified asymptotic analysis method, we find that upon protonirradiation the critical exponents do not fall into any particular universalityclass but lie close to mean field critical exponents ({\gamma} = 1, \b{eta} =0.5). The presence of long-range interactions can be safely assumed for thepristine and irradiated cases of MST examined in this work. Further analysis onthe effective spatial dimensionality reveal that MST remains at d = 3 underproton irradiation transitioning from an n = 1 spin dimensionality to n = 2 andn=3 for 1 x 10^15 and 5 x 10^15 H+/cm^2, indicating an XY interaction and aHeisenberg interaction, respectively. The pair (spin-spin) correlation functionreveals an increase in magnetic correlations at the proton irradiance of 5 x10^15 H+/cm^2. In conjunction, the maximum change in magnetic entropy obtainedfrom isothermal magnetization at 3 T is the largest for 5 x 10^15 H+/cm^2 witha value of 2.45 J/kgK at T = 73.66 K, in comparison to 1.60 J/kgK for pristineMST at T = 73 K. Magnetic entropy derived from zero-field heat capacity doesnot show large deviations across the proton irradiated samples. This suggeststhat the antiferromagnetic coupling between the Mn sites is stable even afterproton irradiation. Such result implies that magnetization is enhanced througha strengthening of the super-exchange interaction between Mn atoms mediatedthrough Te rather than a weakening of the AFM component. Overall, our studyfinds that the magnetic interactions are manipulated the greatest when MST isirradiated at 5 x 10^15 H+/cm^2.
