[en] A general method for obtaining a dyon solution in curved space-time from a known electrically charged solution is presented. Nonabelian dyon is derived, a la Arafune et al., from a corresponding abelian dyon by applying a singular gauge transformation. The Kerr-Newman solution is adopted as an original electrically charged solution and stationary rotating exact Schwinger and Julia-Zee dyon solutions are obtained in abelian and nonabelian cases, respectively. These solutions are characterized by four physical parameters; mass M, angular momentum S, electric charge Q, and magnetic charge PHI. (author)
