“…Thus, a birefringence-induced decrease of the Faraday rotation limits the static and dynamic magneto-optical studies of these materials and causes significant obstacles for their applications. Bearing in mind the importance of the magneto-optical effects for a wide range of applications, such as domain visualization, , probing of the ultrafast magnetic dynamics, sensing, biosensing, , and magnetometry, we focus our current study on the peculiarities of the Faraday effect that arise from the optical anisotropy of an antiferromagnetic crystal.…”

Optical anisotropy is usually treated as an unfavorable condition for the magneto-optical measurements since it is known to diminish the Faraday rotation concerning the case of the isotropic medium. Here we show that the situation could be quite opposite: a phenomenon of birefringence-mediated enhancement of the magneto-optical activity appears if the incident light polarization and angle of incidence are set properly. The present study relies on the experimental, analytical, and numerical studies of iron borate FeBO3 crystals. We demonstrate a significant increase of the magneto-optical activity resulting in nearly 100% magneto-optical light modulation magnitude. The approach applies to other types of birefringent crystals with the magneto-optical response that makes it crucial for various practical applications, including magneto-optical microscopy, pump-probe studies, and others.

“…Bearing in mind the importance of optical measurements of the magnetization states and its applications in domain detection [14], ultrafast dynamics probing [3], sensing [15], biosensing [16,17] and magnetometry [18], we focus our study on the peculiarities of the Faraday effect that arises from the optical and magnetic anisotropy of FeBO 3 crystal. In contrast to the recent studies that exploit the features of the nanoplasmonic [19][20][21][22][23] and nanophotonic [24][25][26] structures, we show that optical * ignatyeva@physics.msu.ru anisotropy of the crystal itself provides a powerful tool for the drastic increase of the magneto-optical effects.…”

Antiferromagnets are promising for magneto-optical light control that could be performed at THz frequencies via excitation of the quasi-antiferromagnetic spin modes. However, most of the antiferromagnetic crystals possess optical anisotropy that is usually treated as an unfavorable condition for the magneto-optical measurements: optical anisotropy is known to diminish the Faraday rotation with respect to the case of the isotropic medium. Here we show that the situation could be quite opposite: a phenomenon of birefringence mediated enhancement of the magneto-optical activity appears if the orientation of the incident light linear polarization is chosen properly. The present study relies on the experimental, analytical, and numerical studies of iron borate FeBO3 crystals. We demonstrate a significant increase of the magneto-optical activity by more than 10 times for 70 • angle between light polarization and incidence plane instead of commonly-used p-or s-polarizations. It provides a unique sensitivity to the in-plane magnetization of FeBO3 that is crucial for the pumpprobe studies, magneto-optical microscopy, and others. The most important practical application of the observed phenomenon is the light modulation with up to 100% efficiency at THz frequencies. The approach is applicable to other types of birefringent crystals with the magneto-optical response.
