(Color online) Raman spectra of undoped (a) and Mn-doped (b) SiC.
(Color online) (a) XRD patterns of undoped, Mn-doped SiC, and pure metallic Mn; (b) SEM image of the Mn-doped SiC.
(Color online) (a) FT curves of Mn K-edge EXAFS oscillation functions k 3χ(k) for the Mn -doped SiC sample and metallic Mn, respectively. (b) Experimental and fitting FT curves of Mn K-edge EXAFS oscillation functions k 3χ(k) for the sample. The fitting was accomplished in the ARTEMIS software.
(Color online) Temperature dependence of the ZFC and FC curves for the sample at 200 and 1000 Oe, respectively. Top inset: temperature dependence of the ZFC and FC curves at 200 Oe. Bottom inset: hysteresis loops of the sample at temperatures of 80 (red) and 300 K (blue).
