title = "Magnetic circular dichroism in Mn 2p core absorption of Ga1-xMnxAs",
abstract = "We have measured the magnetic circular dichroism in the Mn 2p core absorption of ferromagnetic diluted magnetic semiconductor Ga1-xMnxAs with x = 0.025 in the Faraday configuration. The electronic structure parameters for Mn in Ga1-xMnxAs are obtained by fitting the experimental spectra on the basis of the cluster model calculation with considering the configuration interaction. The Mn 3d-As 4p hybridization and the negative weak p-d exchange constant are estimated.",

note = "Funding Information: We thank A. Tanaka for allowing us to use the program for cluster model calculation and the staffs of SPring-8, especially T. Matsushita and T. Nakatani for developing software for MCD measurement. The XAS-MCD measurement was performed under the approval of the Japan Synchrotron Radiation Research Institute (Proposal No. 1999B0369-NM-np). This work was supported by a Grant-in-Aid for COE research of the Ministry of Education, Science, Sports and Culture, Japan.",
