Limits of Solid Solution and Evolution of Crystal Morphology in (La_1-xRE_x)FeO₃ Perovskites by Low Temperature Hydrothermal Crystallization.

ABSTRACT: The crystallization of a new series of A-site substituted lanthanum ferrite materials (La_1-xRE_x)FeO₃ was explored by the hydrothermal method at 240 °C, for rare earth (RE) = Nd, Sm, Gd, Ho, Er, Yb, and Y, with 0 ≤ x ≤ 1. The effect of elemental substitution on the morphological, structural, and magnetic properties of the materials was studied using high-resolution powder X-ray diffraction, energy dispersive spectroscopy (EDS) on the scanning electron microscope, Raman spectroscopy, and SQUID magnetometry. If the radius of the La³⁺ and the substituent ions is similar, such as for Nd³⁺, Sm³⁺, and Gd³⁺, homogeneous solid solutions are formed, with the orthorhombic GdFeO₃-type structure
