Two-dimensional (2D) magnets are materials only a few atomic layers thick that still act as magnets. They show unusual physical properties and are central to research on quantum materials.

What they work on
- Tune the magnetic properties of the room-temperature 2D ferromagnet 1T-CrTe2, especially its in-plane spin alignment, by intercalating guest species between its layers using chemical and electrochemical methods.
- Characterize how intercalation changes the crystal and electronic structure, defect ordering and physical properties of 1T-CrTe2, combining crystal growth, structural chemistry, theoretical calculations and property measurements.
- Fabricate and characterize devices from intercalated 2D magnetic materials, and develop a new quantum materials course for students at the home institution.
More about the research
Chromium ditelluride in its 1T crystal form (1T-CrTe2) stands out because it stays ferromagnetic at room temperature, meaning it holds magnetism like an iron magnet. It also has large magnetic moments and strongly prefers certain magnetization directions. However, its electron spins line up within the layers. This creates strong spin coupling, which limits how the material can be used.
Why it matters
Room-temperature 2D magnets are promising building blocks for quantum materials and future magnetic devices. Showing how chemical intercalation changes the spin alignment of 1T-CrTe2 could make this material easier to use in applications. It could also guide the design of other tunable 2D magnetic materials.
Known grants
