Abstract
<p style='text-indent:20px;'>We construct self-dual codes over <inline-formula><tex-math id="M6">\begin{document}$ \mathbb{F}_{11} $\end{document}</tex-math></inline-formula>, <inline-formula><tex-math id="M7">\begin{document}$ \mathbb{F}_{13} $\end{document}</tex-math></inline-formula>, <inline-formula><tex-math id="M8">\begin{document}$ \mathbb{F}_{17} $\end{document}</tex-math></inline-formula>, <inline-formula><tex-math id="M9">\begin{document}$ \mathbb{F}_{19} $\end{document}</tex-math></inline-formula> and <inline-formula><tex-math id="M10">\begin{document}$ \mathbb{F}_{23} $\end{document}</tex-math></inline-formula> which improve the previously known lower bounds on the largest minimum weights. In particular, the largest possible minimum weight among self-dual <inline-formula><tex-math id="M11">\begin{document}$ [n, n/2] $\end{document}</tex-math></inline-formula> codes over <inline-formula><tex-math id="M12">\begin{document}$ \mathbb{F}_{p} $\end{document}</tex-math></inline-formula> is determined for <inline-formula><tex-math id="M13">\begin{document}$ (p, n) = (19, 24) $\end{document}</tex-math></inline-formula> and <inline-formula><tex-math id="M14">\begin{document}$ (23, 28) $\end{document}</tex-math></inline-formula>.</p>
