X-ray Magnetic and Natural Circular Dichroism from first principles: Calculation of K- and L1-edge spectra
N. Bouldi, N. J. Vollmers, C. G. Delpy-Laplanche +8
An efficient first principles approach to calculate X-ray magnetic circular dichroism (XMCD) and X-ray natural circular dichroism (XNCD) is developed and applied in the near edge r…
