Figure 4

(a,b) C and O K-edge shows XANES spectra of GO with photo-helicity of incident X-rays parallel (μ+) and anti-parallel (μ−) to direction of magnetization, respectively. Inset magnifies π-σ (σ) region of C (O) K-edge XANES spectra with incident X-rays μ+ and μ− to direction of magnetization. Bottom panels present C and O K-edge XMCD spectra of GO.
