Abstract
The effects of chemical ordering in thin film Fe0.5Pd0.5 alloys, deposited by molecular-beam epitaxy directly on a MgO (001) substrate, have been stud ied using magnetic circular x-ray dichroism (MCXD) at the Pd and Fe L-2,L-3 edges. This system exhibits perpendicular magnetic anisotropy if grown in the L1(0) (001) phase and in-plane anisotropy in the disordered gamma phase . We show that MCXD isa sensitive tool for studying variations in the spin and orbital magnetic moments due to changes in the chemical order. We obtai n quantitative results for spin and orbital anisotropies and their variatio ns with chemical order in the Fe0.5Pd0.5 alloy system. [S0163-1829(99)01602 -1].
