Disentanglement of magnetic contributions in multi-component systems by using X-ray magnetic circular dichroism at a single absorption edge

[Comparison of magnetisation] Comparison of the temperature dependence of the magnetisation measured by using a standard SQUID magnetometer and that derived from the magnetisation of the rare-earth and transition-metal sublattices determined from the rare-earth L2-edge XMCD spectra.
X-ray Magnetic Circular Dichroism (XMCD) has proved to be one of the most outstanding tools to study magnetism by incorporating the atomic-element specificity inherent to a core-level spectroscopy. XMCD is a simultaneous fingerprint of the magnetic contributions to the conduction band coming from the different elements in the material. Our approach provides a method of disentangling these contributions that opens the possibility of performing element-specific magnetometry by using a single X-ray absorption edge.
