Magneto-optical property of terbium-lutetium-aluminum garnet crystals

General method for atomistic spin-lattice dynamics with first-principles accuracy

“…20,21 Several studies point at the importance of phononmagnon coupling in a number of dynamical processes such as demagnetization processes, [22][23][24] thermal conductivity, 25,26 magneto-acoustics, [27][28][29] and the spin-Seebeck effect. [30][31][32] The interaction between spin and lattice motion is also central for phenomena observed in magnetoelectric and in multiferroic materials, [33][34][35][36][37][38][39][40] magnetocaloric materials, 41 skutterudites, 42 and antiferromagnetic insulator materials for spintronic devices. 43 Among recent developments on methods for modelling of phonon-magnon coupling can be mentioned a novel combination of atomistic spin dynamics and ab initio molecular dynamics, applied to the paramagnetic phase of the magnetic insulator CrN, 44 and a scheme for massively parallel symplectic integration of spin-lattice dynamics equations of motion.…”

Czochralski Growth, Magnetic Properties and Faraday Characteristics of CeAlO3 Crystals

“…Paramagnetic magneto-optical materials containing rare earth ions (such as Tb 3+ , Eu 2+ and Ce 3+ ) are suitable for use in this band, although their Verdet constants are smaller than those of doped YIG. As is known, crystals [3][4][5][6], glasses [7][8][9] and ceramics [10,11] containing Tb 3+ ions have been extensively investigated as Faraday rotator materials due to its good magneto-optic effect in the visible and near-infrared bands and relatively easy preparation process. However, at the present, the crystals containing Ce 3+ ions have drawn people's attention [12][13][14][15].…”

Study on the Solid and Solution Properties of Sc3+ and Al3+ in (Tb, Sc)3 (Sc, Al)5O12 Crystals Grown by the Czochralski Method

“…Terbium aluminum garnet crystals Tb 3 Al 5 O 12 (TAG) have good properties. , However, due to the non-uniform melt of terbium oxide and aluminum oxide at high temperatures, it is difficult to grow large-size single crystals with a diameter of 40 mm and above by using the Czochralski (Cz) method, , which cannot meet the demand for magneto-optical crystal materials. Researchers try to control the crystal structure by using the doping method, which can make the TAG crystal form a uniform melt at high temperature. , The scandium aluminum garnet crystal Tb 3 Sc 2 Al 3 O 12 (TSAG) was obtained by replacing Al 3+ at the octahedral position in the TAG lattice with Sc 3+ . − The ionic radius of Sc 3+ is 0.0745 nm, which is between 0.0923 nm of Tb 3+ and 0.0535 nm of Al 3+ . It can stabilize the garnet structure and make it possible to grow large-size and high-quality TSAG crystals with the Cz method. − …”
