Iron Phosphorus Trisulfide (FePS3) Powder and Crystals

Product Code M2207C1

Low price, high purity iron phosphorus trisulfide powder and crystals

Suitable for the creation of monolayer and few-layer films, nanosheets and nanoparticle magnetic graphene

Iron phosphorus trisulfide (FePS3) belongs to the family of  transition metal phosphorus trichalcogenides (MPX3). FePS3 contains Fe, S and P which are all earth abundant elements. In its bulk form, FePSis a layer structured antiferromagnetic semiconductor and can be exfoliated into few-layer 2D nanosheets. It is commonly referred to as 'magnetic graphene'.

FePS3 is a good example of a low-temperature 2D antiferromagnetic insulator that can be tuned with pressure into an exotic metallic state. Under compression, the layered structure simultaneously undergoes large in-plane lattice collapses, abrupt spin-crossovers and insulator-metal transitions. Raman spectroscopy reveals that FePS3 exhibits an Ising-type antiferromagnetic ordering down to the monolayer limit, suggesting that intra-layer spin interaction dominates the magnetic structure of FePS3.

We supply low price iron phosphorus trisulfide - or magnetic graphene - powder and crystals.

Bulk single iron phosphorus trisulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation. Single iron phosphorus trisulfide crystals, or films produced from such crystals, are suitable for study using atomic force microscopy or transmission electron microscopy.

Few-layer FePS3 nanosheets and nanoparticles can also obtained from iron phosphorus trisulfide powder by liquid-exfoliation.

Key Product Data

  • High purity, low price iron phosphorus trisulfide
  • Magnetic material with 2D structure (hence 'magnetic graphene')
  • Available in powdered or crystal form

Structure and Properties

After exfoliation of iron phosphorus trisulfide crystal or powder, FePS3 typically has the following properties:

  • ‎Monoclinic (space group: C2/m)
  • Transition metal phosphorus trichalcogenides (MPX3)
  • Antiferromagnetic semiconductor with Ising-type antiferromagnetic ordering down to the monolayer limit
  • Insulator-metal transitions under compression


Iron phosphorus trisulfide (FePS3) single crystals can be used to prepare monolayer and few-layer FePS3 by mechanical or liquid exfoliation. The powdered form is suitable for liquid chemical exfoliation to prepare nanosheets and nanoparticles down to few-layer films.

Structure of Iron Phosphorus Trisulfide

FePS3 is a cation-ordered CdCl2 type low-dimensional layered magnetic semiconductor. FePS3 crystal has a monoclinic structure with the factor group C2h. In each unit cell, the magnetic Fe atoms are octahedrally coordinated to six S atoms with a small trigonal distortion. The P atom is coordinated to three S atoms and one P atom to form a [P2S6]4- unit. The [P2S6]4- units are connected with six Fe atoms, which are arranged in a honeycomb plane structure.
