Zero- and longitudinal-field muon-spin rotation (ZF-$$mu$$SR and LF-$$mu$$SR) measurements were carried out on a multi-layered HgBa$$_2$$Ca$$_4$$Cu$$_5$$O$$_y$$ (Hg-1245) superconductor with $$T$$$$_{rm c}$$ of 108 K. With decreasing temperature, the observed ZF-$$mu$$SR function changed from a Gaussian-type to an exponential-type below 60 K and zero field muon precession was also observed below 45 K. These $$mu$$SR signals are attributed to the development of the antiferromagnetic ordering in inner CuO$$_2$$planes with a low carrier concentration. These results seem to indicate clear evidence that antiferromagnetism microscopically coexists with superconductivity in the Hg-1245 superconductor below 60 K.
