Quantum Anomalous Hall Effect in Two-dimensional Ferromagnetic NpF Monolayer with High Curie Temperature

The Quantum Anomalous Hall Effect (QAHE) is a fascinating phenomenon that combines principles of quantum mechanics and topology, offering a unique pathway for advancements in quantum computing and artificial intelligence. As researchers explore new materials for high-performance applications, the two-dimensional ferromagnetic NpF (Neptunium Fluoride) monolayer has emerged as a promising candidate due to its high Curie temperature and robust QAHE properties. In this article, we will delve into the fundamentals of QAHE, the significance of NpF monolayers, and the potential implications for future technologies.

What is the Quantum Anomalous Hall Effect?

The Quantum Anomalous Hall Effect is characterized by a quantized Hall conductivity in the absence of an external magnetic field. This effect arises from the interplay between spin-orbit coupling and time-reversal symmetry breaking, which are crucial for creating topological states in materials. Unlike the classical Hall effect, where the electric current is perpendicular to both the electric field and the magnetic field, QAHE can occur in ferromagnetic materials under certain conditions.
