Nano CrGeTe₃: Topological Hall Effect in the Metallic State under High Pressure.

ABSTRACT: The ferromagnetic (FM) properties of the van der Waals charge transfer insulator CrGeTe₃ provide a promising avenue for concurrently controlling magnetic and electrical characteristics. This enables the potential integration of devices using nanoscale materials. In this research, we have effectively produced highly stable CrGeTe₃ nanosheets by utilizing a Cr₂Te₃ template. Additionally, we show that the magnetic and electrical characteristics of CrGeTe₃ single crystals can be continuously adjusted through the application of pressure. Electrical transport measurements reveal that CrGeTe₃ transitions from an insulator under ambient conditions to a metallic state at 6.02 GPa. After reaching 25.33 GPa, CrGeTe₃ undergoe
