Breaking New Ground: Quantum Anomalous Hall Effect in Ferromagnetic Metals

The quantum anomalous Hall (QAH) effect has long been a topic of interest in the realm of topological physics. Traditionally thought to only occur in insulators, recent research has uncovered the possibility of realizing the QAH effect in metallic systems as well.

One of the key revelations in this field came from a study demonstrating the existence of a distinct phase of the QAH effect in ferromagnetic metals. This discovery not only expands our understanding of quantum phenomena but also opens up new possibilities for applications in electronics.

Unraveling the Mysteries of Quantum Hall Effect

The quantum Hall effect, first predicted by researchers at the University of Tokyo in 1975, has been a cornerstone of quantum physics exploration. By observing the integer quantization of the Hall conductance in high-purity MOSFETs at ultra-low temperatures, scientists have been able to delve deeper into the realm of quantum effects.

Further studies have revealed the microscopic origins of the Quantum Hall Effect, shedding light on the fractional quantum anomalous Hall effect in multilayer graphene. These findings pave the way for future advancements in the field of quantum physics.

The Future of Quantum Anomalous Hall Effect

Recent developments, such as the tunable quantum anomalous Hall effect in fullerene monolayers, have sparked renewed interest in this area of research. With the potential for observing both integer and fractional quantum anomalous Hall effects in various materials, the future of quantum physics looks promising.

In conclusion, the exploration of the quantum anomalous Hall effect represents a significant breakthrough in topological physics. As researchers continue to push the boundaries of our understanding of quantum phenomena, we can expect to see further advancements in this fascinating field.
