Scientific Achievement
Researchers in the Quantum Materials Program uncovered and manipulated the spin arrangement in a material candidate EuIn2As2, and established its impact on electronic properties.
Significance and Impact
The methodology introduced here offers a way to overcome the challenge that theoretical predictions of exotic phenomena in topological magnetic materials, its experimental validation is often limited by difficulties in determining the magnetic state.
Research Details
- Detected the breaking of rotational symmetry and time-reversal symmetry with two symmetry-sensitive optical experiments
- Combined optics with scattering and theory to uniquely determine magnetic state
- Applied uniaxial strain to reach symmetries required for the exotic electronic state
