We present theoretical and experimental data concerning the possibility of ferromagnetic order in bulk palladium. First principles, self-consistent DFT calculations including spin-orbit coupling performed at 0 show that ferromagnetism occurs in bulk at the optimum lattice constant if is in a hexagonal close-packed (hcp) phase modification. In this phase has, in comparison to in its natural non-magnetic face-centred (fcc) structure, flatter bands at the Fermi level, fulfilling the Stoner criterion for ferromagnetism. We identify these bands in the bulk band structure and probe them with angle-resolved ultraviolet photo-electron spectroscopy in () oriented hexagonal close-packed films deposited on .
