Synthesis and Magnetic Characterization of SolGel‐Derived Submicrometer NaGd(WO₄)₂

Abstract

NaGd(WO 4 ) 2 (NGW) submicrometer powder was derived by solgel method, and its magnetic properties were investigated for magnetic texturing application. The analysis of X-ray diffraction indicates the formation of tetragonal phase. Organic liberation with respect to temperature in the samples and carbon content in the prefired powder was analyzed using FTIR results. Raman spectra confirm the tetrahedral tungstate formation and corresponding vibrations. UV-Vis Reflectance study revealed the corresponding absorption of NGW host and gadolinium ions. The morphology and approximate size of the synthesis powder was observed with SEM micrographs. The paramagnetic nature of NGW was confirmed with EPR, and VSM analysis at room temperature and paramagnetic to antiferromagnetic phase transition was observed around 5 K. Results indicate that NGW powders can be used for magnetic texturing to grow transparent ceramic.
