“…We next performed measurements on single crystals obtained by aligning our largest single crystals into a mosaic arrangement to obtain a total mass of 0.29 mg for analysis. From these data, Figure a, it is evident that spins are aligned along the ab planes (i.e., within the lamellae), similar to what is seen in Ni 2 P 2 S 6 , Co 2 P 2 S 6 , CuCrP 2 S 6 , , and likely CuCrP 2 Se 6 …”

“…This 1D behavior is likely facilitated by the striped cation structure of this particular material (Figure ). Given that AgCrP 2 Se 6 exhibits a hexagonal motif, one would expect long-range AFM ordering more in line with behavior observed by CuCrP 2 S 6 ,, and CuCrP 2 Se 6 …”

“…Quaternary MTPs (i.e., those containing four elements) have a mixture of two different cations which allows for an extra degree of freedom in atomic arrangements. In the sulfide materials, depending on the size ratio between the cations, cations are arranged in stripes (larger difference) or alternating cations (smaller difference). , These trends do not thus far appear to hold true for MSPs, where all known structures exhibit an alternating cation arrangement. Finally, most quaternary MTP/MSP compounds contain a monovalent coinage metal such as Cu + of Ag + which exhibits some degree of mobility and ferroelectric behavior (cf.…”

“…This observation would be surprising given the complex cation ordering present in most other quaternary MTP/MSP materials. Quaternary MTP compounds arrange their different cation types into stripes when the difference between the cations is large (>0.41–0.50 Å); , the striped subclass relieves stresses via a buckled, accordion-like structure, Figure . MSP materials, on the other hand, have a larger volume per P 2 X 6 unit (X = S,Se), thus containing more room inside of the lamellae to accommodate these cations without resorting to the formation of stripes.…”

We have undertaken an extensive study of the structural, magnetic, calorimetric, and optical properties of AgCrP 2 Se 6 , a cleavable van der Waals material in the greater metal thio/selenophosphate family. We have found that this material exhibits a crystal structure of P3 1 12 and is antiferromagnetic below ∼42 K, with spins pointed along the lamellar direction (i.e., the ab plane) rather than along the stacking direction. The magnetic saturation at 5 K is ∼2.7 μ B /Cr. We note the presence of additional indicators of structural rearrangements at higher temperatures from calorimetric, powder diffraction, and Raman analyses, which suggest more complex and possible multiferroic behavior. Our optical reflectance measurements show an indirect bandgap of 1.240 eV and bright defect emission at 694.7 nm from the Cr 3+ sites. Density functional theory calculations of both magnetism and the optical bandgap are in excellent agreement with experimental results. With its magnetic behavior and unique optoelectronic properties, AgCrP 2 Se 6 appears to be a promising candidate for 2D device fabrication.

Antiferromagnetic van der Waals‐type M2P2X6 compounds provide a versatile material platform for studying 2D magnetism and relevant phenomena. Establishing ferromagnetism in 2D materials is technologically valuable. Though magnetism is generally tunable via a chemical way, it is challenging to induce ferromagnetism with isovalent chalcogen and bimetallic substitutions in M2P2X6. Here, we report co‐substitution of Cu1+ and Cr3+ for Ni2+ in Ni2P2S6, creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys spanning a full substitution range (x = 0 to 1). Such substitution strategy leads to a unique evolution in crystal structure and magnetic phases that are distinct from traditional isovalent bimetallic doping, with Cu and Cr co‐substitution enhancing ferromagnetic correlations and generating a weak ferromagnetic phase in intermediate compositions. This aliovalent substitution strategy offers a universal approach for tuning layered magnetism in antiferromagnetic systems, which along with the potential for light‐matter interaction and high‐temperature ferroelectricity, can enable multifunctional device applications.

Multiferroic materials have attracted considerable attention owing to their unique magnetoelectric or magnetooptical properties. Recent discovery of few‐layer van der Waals multiferroic crystals provide a new research direction of controlling the multiferroic properties in the atomic layer limit. However, research on few‐layer multiferroic crystals is limited and the effect of thickness dependent symmetries on those properties are less explored. In this study, we investigated the symmetries and magnetoelectric responses of van der Waals multiferroic CuCrP2S6 by optical second harmonic generation (SHG). Structural and magnetic phase transitions were successfully probed by the temperature‐dependent SHG signals, revealing significant changes by applying the magnetic field reflecting the magnetoelectric effect. Moreover, we found that symmetries and resultant magnetoelectric responses can be modulated by the number of layers. These results offer a new principle of controlling the multiferroicity and indicate two‐dimensional vdW multiferroic material is a promising building block for functional nanodevices.This article is protected by copyright.
