Crystallization of trigonal (Tb,Er)(Fe,Ga)3(BO3)4 phases with hantite structure in bismuth trimolybdate-based fluxes

Abstract

The stability regions of the trigonal (Tb,Er)(Fe,Ga)3(BO3)4 phases are established in (Bi2Mo3O12)-based fluxes. The specific features of heterogeneous nucleation and the subsequent phase transformations during transition to the equilibrium are studied in the vicinity of the boundaries. The temperature modes of single crystal growth on seeds are suggested with due regard for the “nonequilibrium effect.”
