Fig. 3: Spin densities.

Spin densities calculated for relaxed geometrical structures of a CoPd₁₂P₈ and b PdPd₁₂As₈. The yellow surfaces correspond to isovalues of 0.01r_B⁻³. For clarity, the crystal structure close to the central ion is sketched in addition (Pd in red, O in blue, P or As in grey).
