Are X-Ray Magnetic Circular Dichroism and Circular Dichroism the Same
Although X-ray Magnetic Circular Dichroism (XMCD) and Circular Dichroism (CD) are both critical techniques for analyzing the electronic properties of materials, they measure different physical quantities and are applied in distinct fields.
Circular Dichroism (CD) primarily serves as a method for studying molecular structures, with significant applications in the fields of biological macromolecules and supramolecular chemistry. By assessing the differential absorption of left and right circularly polarized light, CD provides insights into molecular structures, as optical activity is intrinsically linked to molecular chirality.
Conversely, X-ray Magnetic Circular Dichroism (XMCD) is a central technique for investigating the magnetic properties of materials. It involves measuring the differential absorption of left and right circularly polarized X-rays at specific energies, yielding information about material magnetic moments. This technique is closely associated with the study of material magnetism and is extensively employed in the research of thin film magnetism, nanomagnetism, and strongly correlated electron systems.
