Topological insulators act as electrical insulators on the inside but conduct electricity along their surfaces. Researchers study some of these insulators' exotic behavior using an external magnetic field to force the ion spins within a topological insulator to be parallel to each other. This process is known as breaking time-reversal symmetry. Now, a research team has created an intrinsic ferromagnetic topological insulator. This means the time-reversal symmetry is broken without applying a mag...
