半导体铁磁体CrSiTe 3是一个有前途的候选人,二维磁铁简单地剥离到单层。为了理解薄膜样品的磁性行为和可能的应用,有必要建立块体中磁性的性质。在这项工作中,在顺磁到铁磁相变的单晶CrSiTe 3的临界行为进行了研究体磁化测量。用修正的Arrott图、Kouvel-Fisher图和临界等温线分析等方法求得了临界指数(β = 0.170 ± 0.008,γ = 1.532 ± 0.001,δ = 9.917 ± 0.008)和临界温度TC = 31.0K。我们的分析表明,所确定的指数匹配以及从重正化群方法的结果计算的二维伊辛模型与长程相互作用。
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.
