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