Abstract
Elevating the temperature needed to realize the quantum anomalous Hall effect (QAHE) to above 77 K or higher is the key to practical applications of the effect as well as many others based on it. Here, we briefly review the recent progresses, especially the experimental ones, on searching for magnetic topological insulators that can exhibit the QAHE at higher temperature. Based on our understanding of these results, we will give the principles and roadmap for designing and constructing high-temperature quantum anomalous Hall systems.
