Abstract
The semiconducting ferromagnet CrSiTe3 is a promising candidate for two-dimensional magnet simply by exfoliating down to single layers. To understand the magnetic behavior in thin-film samples and the possible applications, it is necessary to establish the nature of the magnetism in the bulk. In this work, the critical behavior at the paramagnetic to ferromagnetic phase transition in single-crystalline CrSiTe3 is investigated by bulk magnetization measurements. We have obtained the critical exponents (β = 0.170 ± 0.008, γ = 1.532 ± 0.001, and δ = 9.917 ± 0.008) and the critical temperature TC = 31.0 K using various techniques such as modified Arrott plot, Kouvel-Fisher plot, and critical isotherm analysis. Our analysis suggests that the determined exponents match well with those calculated from the results of renormalization group approach for a two-dimensional Ising model coupled with long-range interaction.

Summary
The semiconducting ferromagnet CrSiTe3 is a promising candidate for two-dimensional magnet by exfoliating down to single layers. One of the primary goals in this area is to develop ferromagnetic (FM) semiconductors, which are eagerly needed in next-generation nano-spintronics[6,7,8], and exhibit unusual magnetism that are of great interest on its own[9] Within this context, the intrinsic semiconducting ferromagnet CrSiTe3 has generated considerable interest recently because first principle calculations predict the important coexistence of ferromagnetic and semiconducting properties upon exfoliating down to single layers in this material[10]. Based on the spin wave analysis, they argued that the spins should be Heisenberg-like[15] These controversial results prompt us to perform an extensive magnetization measurement to investigate the critical behavior of CrSiTe3, expecting the universality class to which the material belongs to gives important clues for the understanding of the unusual magnetism in this material. Our analysis indicate that the obtained critical exponents are in good agreement with those calculated from the results of renormalization group approach for 2D Ising model coupled with long-range interaction
