“…As previously observed by Crossley and co-workers [5,6] in the 100-450 K temperature range, the rotation in TbIG is much larger than that of YIG (for example, at 295 K, OF (TbIG) = 435 deg. cm OF (YIG) = 285 cm-1 1 at 1.…”

Temperature and high magnetic field dependence of the Faraday rotation in the terbium iron garnet

1979

The Faraday rotation of terbium iron garnet at 1.15 μ wavelength is presented. The experimental results have been obtained along the [111] easy direction both in low d.c. field 20 kOe as a function of temperature between 4.2 and 300 K and at room temperature as a function of the applied field (up to 1 200 kOe). The results are analysed in terms of magnetic and electric dipole contributions from the three magnetic sublattices. The Fe3+ contributions are considered to have the same values as in YIG and the total Tb3+ contributions are obtained. The contribution of the magnetic dipole transitions of the R.E. has been calculated when the influence of the crystalline field effect on the Landé factor is taken into account; the electric dipole contribution is found to be strongly temperature and magnetic field dependent

“…Above 1100 nm, a ferrimagnetic material yttrium iron garnet (YIG) crystal and its RE-substituted compositions represent the established materials for the FDs, as they have been investigated since the 1960s [65,152]. The RE-substituted iron garnets possess very high Verdet constant [153][154][155][156] and low saturation magnetization [157], which is the main reason for its wide utilization for low-power applications in telecommunications, medical field or integrated magneto-optical devices [4].…”

Verdet Constant of Magneto-Active Materials Developed for High-Power Faraday Devices

We review the progress in the investigation of the Verdet constant of new magneto-active materials for the Faraday-effect-based devices used in high-power laser systems. A practical methodology for advanced characterization of the Verdet constant of these materials is presented, providing a useful tool for benchmarking the new materials. The experimental setup used for the characterization is a flexible and robust tool for evaluating the Faraday rotation angle induced in the magneto-active material, from which the Verdet constant is calculated based on the knowledge of the magnetic field and the material sample parameters. A general model for describing the measured Verdet constant data as a function of wavelength and temperature is given. In the final part of this review, we present a brief overview of several magneto-active materials, which have been to-date reported as promising candidates for utilization in the Faraday devices. This overview covers room-temperature investigations of the Verdet constant of several materials, which could be used for the ultraviolet, visible, near-infrared and mid-infrared wavelengths.

Understanding magnetooptics in cylindrical structures presents interest in the development of magnetic sensor and nonreciprocal devices compatible with optical fibers. The present work studies wave propagation in dielectric circular cylindrical structures characterized by magnetic permeability and electric permittivity tensors at axial magnetization. The Helmholtz equations deduced from the Maxwell equations in transverse circularly polarized representation provide electric and magnetic fields. With the restriction to terms linear in off-diagonal tensor elements, these can be expressed analytically. The results are applied to magnetooptic (MO) circular cylindrical waveguides with a step refractive index profile. The nonreciprocal propagation is illustrated on waveguides with an yttrium iron garnet (YIG) core and a lower refractive index cladding formed by gallium substituted yttrium iron garnet (GaYIG) at the optical communication wavelength. The propagation distance required for the isolator operation is about one hundred micrometers. The approach may be applied to other structures of cylindrical symmetry in the range from microwave to optical frequencies.
