| 英文摘要 | The van der Waals ferromagnet CrTe2 is a promising candidate due to its high Curie temperature at room temperature and large magnetic moment. Furthermore, the magnetic anisotropy can be adjusted by the concentration of Cr ion. To understand the ferromagnetic exchange mechanism involving the self-intercalation of Cr atoms into CrTe2, we systematically investigated the critical behavior of Cr1.2Te2. We obtained a set of reliable critical exponent values (beta = 0.882(3), gamma = 1.201(6), and delta = 2.36(4)) by using diverse analytical methods. The critical behavior suggests a three-dimensional magnetic exchange mechanism in Cr1.2Te2, with the exchange distance decaying approximately as J(r) approximate to r(- 4.70). This behavior closely resembles the 3D Heisenberg model with long-range magnetic coupling. |
