Abstract

Magnetism in van der Waals (vdW) materials has recently garnered significant attention due to their potential for advanced applications. In this study, we investigate the magnetic transition in layered MPSe3 (M = Fe, Mn) bulk flakes utilizing temperature-dependent Raman spectroscopy. Our findings reveal unique features in the Raman spectrum that are strongly correlated with the antiferromagnetic ordering in MPSe3. We analyze the spin-dependent Raman scattering modes in MPSe3 by applying the Suzuki–Kamimura formalism. Consequently, our comparative analyses of the spin correlation function and the reduced magnetization provide compelling evidence of the 2D Ising characteristic especially in FePSe3. Our results clearly show the potential of MPSe3 as a prominent platform for exploring fundamental aspects of low-dimensional magnetism.
