Strain control of altermagnetic devices (A12*)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The joint theory-experiment project will explore how selected strain affects the key altermagnetic properties in a choice of materials and measure the changes to the electronic and magnonic-band splitting. We will use direct spectroscopy and transport measurements, complemented by theoretical modeling. The project will explore how strain can be used to trigger phase transitions between altermagnetic and other phases, and will study a piezomagnetic effect that is unique to altermagnets.
