摘要:
X-ray magnetic circular dichroism spectra at the K edge of Mn in the ferromagnetic phases of Mn3GaC and Mn3ZnC are calculated by taking account of the spin-orbit interaction (SOI) in the LDA scheme. The calculated spectra show excellent agreement with the recent experiment, demonstrating that they arise from the p orbital polarization. We make clear the mechanism of its induction by selectively turning off the SOI on specified states. (C) 2003 Elsevier B.V. All rights reserved.
