Monash researchers predict light can switch magnetism and topology in MnBi2Te4
First-principles calculations model a terahertz-driven transition in an atomically thin material; experiments have yet to test the prediction.

Why it matters
The calculations point to a way to control magnetic order and electronic topology together with light in atomically thin MnBi2Te4, giving experiments a defined mechanism to test.
Researchers at Monash University predict that a pulse of light could switch both the magnetic order and electronic topology of atomically thin MnBi2Te4, turning it from an antiferromagnet into a ferromagnet with conducting edge states. The result, published in ACS Nano on October 23rd, comes from first-principles calculations.…
