Due to the explosive increase in the amount of information generated throughout our daily lives, one of the key challenges of our society will be storing and manipulating data with high energy efficiency. One promising approach to solving this grand energy consumption challenge is exploring new data storage and computing technologies based on ultra-thin antiferromagnetic materials. The promise of antiferromagnetism lies in the absence of net magnetization, which increases the achievable density of storage, while the large exchange interactions could enable operation speeds in the terahertz regime. Supported by the CEI award, I will apply a variety of optical techniques to probe the exotic magnetoelectric effects created by a moiré superlattice structure for energy efficient devices.
