Transition-metal phosphochalcogenides MPSe3 (M = Fe, Ni, Mn) are important layered van der Waals materials with rich magnetic and electronic behavior. Among them, FePSe3 is a much investigated layered antiferromagnet with strong potential for applications in two-dimensional spintronics and quantum devices.
Here, we use an additive-free chemical vapor transport technique for growth of single crystals of FePSe3. Single crystals reach up to 3 mm in length and show nearly ideal atomic ratio composition in energy-dispersive x-ray spectroscopy. Magnetic measurements reveal an antiferromagnetic transition around 120 K. We studied the effect of substitution at the Fe site on the anistropic magnetism. We will discuss how substituted Fe1−xMxPSe3 single crystals can be prepared and how substitution at the Fe site affects the anisotropic magnetism.
