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

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 demonstrate the strong coupling of both magnons and phonons to terahertz (THz)
frequency electromagnetic (EM) waves confined to a photonic crystal (PhC) cavity. Our …

Magnon-polaritons are shown to play a dominant role in the propagation of terahertz (THz)
waves through TmFeO3 orthoferrite, if the frequencies of the waves are in the vicinity of the …

The high-frequency properties of a composite resonator comprised single crystal iron borate
(FeBO 3), a canted antiferromagnet with a weak ferromagnetic moment, and a …

Ferrites are widely used in the preparation of basic components that function within the
microwave band. Compared with ferromagnetic ferrites, which possess a weak internal …

Time domain spectroscopy with terahertz (THz) pulses is a powerful technique in
characterizing material properties. THz technology is still developing and many optical …

Strong coupling between light and matter occurs when the two interact such that new hybrid
modes, the so-called polaritons, are formed. Here, we report on the strong coupling of both …

Magnetic and dielectric resonances in the sub-terahertz (sub-THz) frequency range are
observed in pure and Al-substituted hexagonal barium ferrite. A resonator based on …

Excitation of antiferromagnetic resonance (AFMR) in a HoFeO 3 crystal combined with a split
ring resonator (SRR) is studied using terahertz (THz) electromagnetic pulses. The magnetic …
