Synthesis of composite single crystal structures on the basis of iron borate for fundamental studies and practical applications

Abstract

Abstract Composite single crystal structures based on iron borate FeBO3, namely diamagnetically diluted iron-gallium Fe1-xGaxBO3 and iron-aluminium Fe1-xAlxBO3 borates with low x-values, as well as doped GaBO3:Ni single crystals with Ni 0.1-0.01 mass %, have been synthesized using modified flux growth technique. Two technological modes that allowed improving the quality of the samples have been developed: crystallization in (1) open and (2) closed crucibles. Thin magnetic film of iron borate on a diamagnetic gallium borate substrate have been synthesized by liquid-phase epitaxy route.
