Implication

Spectroscopy experiment reveals intrinsic Ising-type antiferromagnetic ordering in monolayer FePS3, indicating that interlayer coupling minimally influences magnetic phase transitions.

Key Points

To experimentally investigate intrinsic magnetic ordering down to the two-dimensional monolayer limit in FePS3.
Monitored temperature-dependent zone-folding Raman peaks across sample thicknesses ranging from bulk crystal to single monolayer.
Compared experimental magnetic transition profiles to the theoretical two-dimensional Onsager order-disorder model.
Identified intrinsic Ising-type antiferromagnetic ordering persisting down to the isolated monolayer limit.
Demonstrated that the transition temperature remains virtually invariant across thickness variations from bulk down to monolayer at TN ~ 118 K.
