Parameters of the effective NN exchange model obtained by fitting the DFT results for hcp-Pd/Fe/Ir(111) and fcc-Pd/Fe/Ir(111) and values from the literature.

	J eff	D eff	K
hcp fit	6.44	1.2	0.8
fcc fit	3.68	1.39	0.7
Ref.24	2.95	0.8	0.4
Ref.26	3.5	1.1	0.5

For hcp D _eff has been chosen as the NN DFT value (cf. Table 1). Sign convention as in Table 1. The coefficients are given in meV.
