Experimental study demonstrates tunable magnetoelectricity and polarity in van der Waals CuCr1-xFexP2S6, indicating pathways for designing high-performance two-dimensional multiferroics.
< 0.5, we observed both magnetic-dielectric coupling and second harmonic generation (SHG) effects. However, these effects were absent at higher doping levels. Furthermore, our analysis revealed a distinct odd-even dependence of SHG, suggesting the presence of interlayer symmetry-breaking coupling. These findings advance our understanding of two-dimensional (2D) multiferroic materials and lay the groundwork for designing and optimizing magnetoelectric coupling materials with enhanced performance.
