Growth of fibrous YIG single crystals by the self-adjusting solvent FZ method

Growth mechanism of incongruently melting terbium aluminum garnet (Tb3Al5O12; TAG) single crystals by laser FZ method

“…Then the TAP phase is left behind, and the TAG crystal is grown through the solvent. This mechanism is similar to 'the self-adjusting solvent growth' previously reported on YIG [4], but the compensated solvent is quite different, i.e., the peritectic point for YIG and the eutectic point for TAG. If x value of the solvent is 0.22, the molar ratio of decomposed TAP and the solvent is calculated as 1:1.6.…”

Growth of terbium aluminum garnet (Tb3Al5O12; TAG) single crystals by the hybrid laser floating zone machine

“…1. In the study of YIG growth [5], we proposed the self-adjusting solvent FZ method. Likewise, TAG might be grown through solvents occurred by the selfadjusting reaction.…”

“…During our research into the incongruent melting of YIG rod crystals [5][6][7][8], we realized that the laser floating zone (FZ) method has good potential to grow other incongruent materials. Moreover, crystals grown by the laser FZ method have a typically rod-like shape and are thought to be suitable for optical device applications because the light can travel through the cylindrical shape without complicated processing.…”

Characterization of the growth mechanism of YIG crystal fibers using the laser heated pedestal growth method

“…So far, techniques to obtain YIG single-crystals have included the flux method [1][2][3], the float zone method (FZ) [4][5][6][7], the laser heated pedestal growth (LHPG) method [8][9][10][11] and the liquid phase epitaxial (LPE) method [12]. However, other phases such as YFeO 3 , Fe 3 O 4 and Fe 2 O 3 [13] can easily appear in the grown YIG crystals, which degrades their magneto-optical properties.…”

“…They also mentioned that the solvent is not always necessary, because a self-adjustment of the solvent will occur automatically. Sekijima et al [8] mentioned that there are some problems in using the TSFZ method to grow YIG crystal by the LHPG method, for example, the holding of a tiny amount [14]. of solvent at the seed during the growth process and the preparation of a solvent with an accurate composition on the scale of the seed and feed rods.…”
