Transition metal phosphorus sulfides (TMPS3) are a family of the layered magnetic materials. Due to the layered structure and the rich spectrum of the magnetic structure [1], TMPS3 has been thought to be a good playground for testing two-dimensional magnetism in real world experiments [2]. It was found that the antiferromagnetic order in FePS3 remains down to the monolayer limit [3, 4], which was soon followed by the discovery of two-dimensional ferromagnetism in CrI3 [5] and Cr2Ge2Te6 [6]. More recently, the existence of the magnetic ordering in few-layer TMPS3 has been investigated in experiments [7, 8]. In this contribution, we present an in-depth investigation of the magnetic structure of few-layer TMPS3 based on the results of our first-principles calculations.
