We have performed X-ray photoemission spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and resonant photoemission spectroscopy (RPES) measurements of Mn-implanted 3-SiC (3-SiC:Mn) and carbon-incorporated Mn $_{5}$ Si $_{2}$ (Mn $_{5}$ Si $_{2}$ :C). The Mn 2 core-level XPS and XAS spectra of 3-SiC:Mn and Mn $_{5}$ Si $_{2}$ :C were similar to each other and showed "intermediate" behaviors between the localized and itinerant Mn 3 states. The intensity at the Fermi level was found to be suppressed in 3-SiC:Mn compared with Mn $_{5}$ Si $_{2}$ :C. These observations are consistent with the formation of Mn $_{5}$ Si $_{2}$ :C clusters in the 3-SiC host, as observed in a recent transmission electron microscopy study.
