DFT calculations. Bar graph of the second-order perturbative contribution of the spin-orbit interaction to the MCA energy at the interfacial atomic sites of (a) Co and (b) Pd for the Pd(8 ML)/Co(4 ML), using a_‖ = 0.391 nm. Spin-resolved local density of states (LDOS) of the d(xy, x² − y²) and d(yz, zx) states for the interfacial (c) Co and (d) Pd sites, for the Pd(8 ML)/Co(4 ML), using a_‖ = 0.391 nm. (e) A schematic of the electron hopping in Co and Pd at the interface. 3d(xy, x² − y²) orbitals in Co and both Pd 4d(xy, x² − y²) and 4d(yz, zx) orbitals are illustrated.
