概要

• 論文の詳細を見る

• N K-, O K- and Co L_<III, II>-edge X-ray magnetic circular dichroism (XMCD) was investigated for NO adsorbed on ultrathin fcc-Co (001) films which show both in-planar and perpendicular magnetic anisotropies. Large suppression of spin and orbital magnetic moments of Co was observed upon NO adsorption. Both N and O K-edge XMCD spectra show negative signs at the NO 2π^* resonance, irrespective of in-plane and perpendicular magnetic anisotropies. This finding implies the parallel alignment of the NO 2π^* orbital magnetic moments with the total magnetization. The results are comparatively discussed with the previous words on CO on Co and Ni films and are interpreted by a simple chemical bonding scheme.
