Abstract: Manganese ferrite MnFe<subscript>2</subscript>O<subscript>4</subscript> was synthesized by gel combustion synthesis using tris(hydroxymethyl)aminomethane (TRIS) as a fuel upon variation of oxidizer-to-fuel ratio Ψ and characterized by XRD, Raman spectra, and vibrating sample magnetometry (VSM). The measured values of saturation magnetization M<subscript>s</subscript> = 27.70 emu g<superscript>–1</superscript> and coercivity H<subscript>c</subscript> = 86.87 Oe are indicative of superparamagnetiс behavior of synthesized materials. Our results also show that TRIS could be readily used as an alternative fuel to synthesize spinel ferrites through a one-step process of solution combustion synthesis. [ABSTRACT FROM AUTHOR]
