| Description | Journal: Journal of Physics: Conference Series Transverse-geometry x-ray magnetic circular dichroism (TXMCD) measurements on Au/Co-staircase/Au(001) reveal the orbital origin of intrinsic in-plane magnetic anisotropy A gigantic TXMCD was successfully observed at the Co $L_{3,2}$ edges for Co thickness $(t_{C0}$) in the 2-monolayer regime. A TXMCD-sum-rule analysis shows a remarkable enhancement of an orbital-moment anisotropy $(Δm_{orb}$) and of an in-plane magnetic dipole moment (m^{||}$_{T}$). Both $Δm_{orb}$ and m^{||}$_{T}$ exhibit close similarity in $t_{Co}$ dependence, reflecting the in-plane magnetic anisotropy These observations evidence that extremely strong, intrinsic, in-plane magnetic anisotropy originates from the anisotropic orbital part of the wave function, dominating the dipole-dipole-interaction-derived, extrinsic, in-plane magnetic anisotropy. |
