“…The value is easy to obtain when one transition is dominant. If several transitions are involved in the Faraday effect, this value can serve as an indicator of the spectral region in which the transition is located [20]. The apparent transition wavelength can be derived from the slope and horizontal intercept of the Van Vleck plot.…”

“…TM containing glasses have been studied in detail for their magnetic properties [10][11][12][13][14][15]. On the other hand, their magneto-optical (MO) properties remain -qualitatively as well as quantitatively -poorly understood and today's MO applications rely solely on RE (Tb 3+ ) loaded glasses [16][17][18][19][20]. This may at least partially be related to the difficulty of finding a suitable matrix material in which the TM species can be stabilized in the desired valence state, coordination number and molar quantity, and which still exhibits a wavelength range with sufficient optical transparency for a magneto-optical application.…”

Transition metal ions such as Mn 2+ , Fe 2+ , or Co 2+ provide an interesting alternative to rare earth dopants in optically active glasses. In terms of their magneto-optical properties, they are not yet very well exploited. Here, we report on the effect of Mn 2+ on Faraday rotation in a metaphosphate glass matrix along the join Mn x Sr 1-x (PO 3 ) 2 with x = 0...1. Mn 2+ shows small optical extinction in the visible spectral range and, compared to other transition metal ions, a high effective magnetic moment. At high Mn-levels, however, the magneto-optical activity of Mn 2+ is strongly quenched due to ionic clustering. The magnetic properties of the heavily Mn 2+ -loaded phosphate matrix are dominated by a superexchange interaction in the Mn 2+ -O-Mn 2+ bridge with antiparallel spin alignment between Mn 2+ and O 2species. The apparent paramagnetic potential of Mn 2+ species can therefore not be exploited at room temperature.

“…A lot of experimental studies on the spectroscopic and optical properties of these materials have been performed, while a theoretical treatment is lacking in the literature. [23][24][25][26][27][28][29][30][31][32][33][34][35] Recently, Chaudhury et al 23 have studied the magneto-electricity and magneto-striction in TmAl 3 (BO 3 ) 4 and concluded that the magneto-electricity is related to the piezoelectric effect of the non-centrosymmetric structure. The giant magnetoelectric effect in HoAl 3 (BO 3 ) 4 has been found to increase with decreasing magnetic anisotropy.…”

The electronic and optical properties of TbAl3(BO3)4 are determined using density functional theory. The calculated total magnetic moment of 5.96 μB is close to the expected moment of Tb3+. The frequency dependent dielectric function, refractive index, extinction coefficient, absorption, optical reflectivity, and energy loss function are explained in terms of the transitions between the valence and conduction bands. We find very high Kerr angles for ultraviolet light and potential for extension, even into the visible range by band structure design.

“…), which, however, exhibit only very small values of the Verdet constant because of their diamagnetic character. The following research was therefore focused more on various materials containing rare-earth (RE) paramagnetic ions, which were reported to have high magneto-optical characteristics [62][63][64][65]. In this manner, several RE-containing glasses were investigated as possible magneto-active materials for the UV FDs, with the cut-off wavelengths equal to ∼200-300 nm [66][67][68].…”

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.
