“…It has been found that magnetic anisotropy could open up an excitation energy gap to counteract the enhanced thermal fluctuations in low dimensional materials [10]. Different from conventional thin films [11], 2D materials bound only by van der Waals (vdW) interactions offer more precise manufacturing control and reproducibility [12,13].…”

Pressure-induced transitions in FePS$_3$: Structural, magnetic and electronic properties

et al. 2023

FePS_33 is a prototype van der Waals layered antiferromagnet and a Mott insulator under ambient conditions, which has been recently reported to go through a pressure-induced dimensionality crossover and an insulator-to-metal transition. These transitions also lead to the appearance of a novel magnetic metallic state. To further understand these emergent structural and physical properties, we have performed a first-principles study using van der Waals and Hubbard UU corrected density functional theory including a random structure search. Our computational study attempts to interpret the experimental coexistence of the low- and intermediate-pressure phases and we predict a novel high-pressure phase with distinctive dimensionality and different possible origins of metallicity.

“…Two-dimensional (2D) van der Waals (vdW) magnetic materials are increasingly recognized for their potential application in next-generation spintronic devices. − These materials in atomically thin forms give rise to a controlling magnetic order and physical properties by gate bias, strain, and proximity effects. − To explore novel materials and the physics of magnetism at the 2D limit, both intrinsic magnetic and magnetically doped 2D vdW materials have been synthesized and investigated. ,− Whereas the latter class requires sophisticated efforts in designing and investigation, the exploration of intrinsic 2D vdW magnetic materials relies on the available bulk forms like ferromagnetic insulating CrBr 3 and CrI 3 , semiconducting CrGeTe 3 , metallic Fe 3 GeTe 2 , and antiferromagnetic insulating MPX 3 (M = Fe, Mn, and Ni, X = S and Se) systems. ,− In most of these materials, the long-range magnetic order is retained in atomically thin forms, and in some cases like CrI 3 , the inter-layer magnetic interactions can be tuned from FM to AFM by mediating the layer number . Furthermore, the antiferromagnetic order in MPX 3 can assist in the formation of coherent excitons, , indicating an appropriate family of materials to investigate the Bose–Einstein condensation of excitons .…”

Although magnetic order is suppressed by a strong frustration, it appears in complex forms such as a cycloid or spin density wave in weakly frustrated systems. Herein, we report a weakly magnetically frustrated two-dimensional (2D) van der Waals material CrPSe3. Polycrystalline CrPSe3 was synthesized at an optimized temperature of 700 °C to avoid the formation of any secondary phases (e.g., Cr2Se3). The antiferromagnetic transition appeared at T N ≈ 127 K with a large Curie–Weiss temperature θCW ≈ −301 K via magnetic susceptibility measurements, indicating weak frustration in CrPSe3 with a frustration factor of f (|θCW|/T N) ≈ 2.4. Evidently, the formation of a long-range incommensurate antiferromagnetic order was revealed by neutron diffraction measurements at low temperatures (below 120 K). The monoclinic crystal structure of the C2/m symmetry is preserved over the studied temperature range down to 20 K, as confirmed by Raman spectroscopy measurements. Our findings on the incommensurate antiferromagnetic order in 2D magnetic materials, not previously observed in the MPX3 family, are expected to enrich the physics of magnetism at the 2D limit, thereby opening opportunities for their practical applications in spintronics and quantum devices.

“…An earlier proposal is to place the graphene on an antiferromagnetic, perovskite BiFeO 3 , [38] which, however, leads to ferromagnetic exchange in graphene. Fortunately, recent first-principles calculations [23,[39][40][41] suggest that graphene on an Ising AFM MnPSe 3 [42,43] would be a realistic platform for the staggered exchange coupling. This provides opportunities to investigate new physics in graphene with proximitized AFM.…”

We systematically investigate the phonon dichroism in proximitized graphene with broken time-reversal symmetry. We find that in the absence of any type of spin-orbit coupling, phonon dichroism vanishes. Linear and circular phonon dichroism occur in the presence of uniform (staggered) intrinsic spin-orbit coupling and ferromagnetic (antiferromagnetic) exchange coupling. All these situations can be distinguished by their specific behaviors of phonon absorption at the transition point. Our finding provides new possibilities to use phonon dichroism to identify the form of spin-orbit coupling and exchange coupling in proximitized graphene on various magnetic substrates.
