摘要：

Multiferroic composites with the general formula (1-x) GaFeO3—(x) Co0.4Zn0.6Fe2O4 (x = 0.0, 0.1, 0.3, and 1) were prepared by mixing chemically synthesized GaFeO3 and Co0.4Zn0.6Fe2O4 powders to investigate their room-temperature multiferroic properties. Rietveld refinement of X-ray diffraction data confirmed the presence of both phases in the composites, with no detectable impurities and expected stoichiometric compositional ratios. Temperature-dependent magnetization, M(T) and field-dependent magnetization, M(H) of the composites show an enhancement in magnetization and magnetic transition temperature, (TN)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$({T}_{N})$$\end{document} compared to that of GaFeO3. Dielectric and ferroelectric measurements performed at room temperature over a 1 Hz to 1 MHz frequency range demonstrated improved dielectric properties relative to the individual parent compounds.
