Layered metal thio- and selenophosphates (MTPs) are a family of van der Waals gapped materials that exhibit a multitude of functionalities in terms of magnetic, ferroelectric, and optical properties. Despite the recent progress in terms of understanding the material properties of these compounds, the potential of MTPs as a material class yet needs further scrutiny, especially in terms of nonlinear optical properties. Recent reports of efficient low-order harmonic generation and extremely high third-order nonlinear optical properties in MTPs suggest the potential application of these materials in integrated nanophotonics.

- The research investigates how manipulating spin-phonon coupling in two-dimensional van der Waals ferromagnetic semiconductors can enhance magnetism, opening new possibilities for spintronic devices.
- The study uses tetrabutyl ammonium (TBA) as an intercalant to show its effects on the magnetic and electronic properties of CrGeTe, revealing increased ferromagnetic Curie temperature through temperature evolution of Raman modes and magnetization measurements.
- The findings point to significant electron transfer from TBA to Cr, emphasizing the importance of spin-phonon interaction and magnetic ordering in understanding and controlling magnetism in layered structures.
Research in two-dimensional layered materials (2DLMs) has exploded over the past several years for a variety of applications in photonics and optoelectronics. The 2D nature of these materials allows for a very local electronic probe of material as well as flexible integration with other functional components. Herein, using the femtosecond Z-scan technique, we report a giant two photon absorption (TPA) process and its saturation in the van der Waals gapped silver scandium thiophosphate (AgScPS) crystal.
