Using first-principles calculations, we predict that tunable ferroelectricity can be realized in
oxide perovskites with the Grenier structure and ordered oxygen vacancies. Specifically, we …

Strong coupling of electromagnetic cavity fields with antiferromagnetic spin waves in
hematite (α-Fe 2 O 3) is achieved above room temperature. A cube of hematite is placed in a …

We report on magneto-optical studies of the quasi-two-dimensional van der Waals
antiferromagnet FePS3. Our measurements reveal an excitation that closely resembles the …

Coupling of space-separated resonators is interesting for quantum and communication
technologies. In this work, we show that antiferromagnetic resonance in separated parallel …

The terahertz (THz) domain represents an important part of the electromagnetic spectrum,
with potential applications stretching from medical imaging, non-destructive testing to high …
