Growth and magneto-optical properties of Na0.37Tb0.63F2.26 cubic single crystal

Crystals of Na 0.37 Tb 0.63 F 2.26 solid solution with a fluorite structure have been grown from melt by the Bridgman technique. The measured values of the Verdet constant are V = 0.35 ± 0.02 and 0.105 ± 0.01 arcmin/(Oe cm) for λ = 633 and 1060 nm, respectively. The dispersion of the Verdet constant is studied in the range of 380–1060 nm. The Na 0.37 Tb 0.63 F 2.26 crystal is somewhat inferior to the previously studied noncubic fluoride crystals containing Tb 3+ ions yields by V (λ) and is close to KTb 3 F 10 crystal in totality of properties.
