| Abstract | Quasi-2D layered Cr4Te5 thin film has attracted great attention because it possesses the high Curie temperature close to room temperature and relatively large saturation magnetization. However, the magnetic interactions and the nature of magnetic phase transition in the Cr4Te5 film have not been explored thoroughly. In this paper, we focused on the critical behavior of its magnetic phase transition through the epitaxial Cr4Te5 film fabricated by pulsed laser deposition (PLD). The final critical exponents beta = 0.359(2) and gamma = 1.54(2) were obtained by linear extrapolation together with Arrott-Noakes equation of state, and their accuracy was confirmed by using the Widom scaling relation and scaling hypothesis. We find that some magnetic disorders exist in the Cr4Te5 film system, which is related to Cr4Te5 critical behavior why its critical behavior is quite far from any conventional universality class. Furthermore, we also determined that the Cr4Te5 film exhibits a quasi-2D long-range magnetic interaction. Finally, the itinerant ferromagnets of Cr4Te5 films were confirmed by the Takahashi's self-consistent renormalization theory of spin fluctuations. Our work provides a new idea for understanding the mechanism of magnetic interactions in similar 2D layered films. |
