Fig. 4: Experimental X-ray absorption spectra.

Normalized experimental X-ray absorption near-edge structure (XANES, black lines) and X-ray magnetic circular dichroism (XMCD, red lines) at the Pd M3,2 and O K absorption edges of CoPd12P8 a, FePd12P8 b, FePd12(PhAs)8 c and PdPd12As8 d in static magnetic fields of ±6 T at a temperature of 4.3–4.6 K. XMCD spectra were multiplied by a factor of 100.
