Unveiling Magnetic Materials with Cutting-Edge Synchrotron Tools

Magnetism has become ubiquitous in our daily live. The prototypical horse-shoes magnet has evolved to generate different families of magnetic devices like electro-magnets, superconductive magnets, or more complex structure like composite magnetic materials used to store data in computers.

On the other hand, since their discovery, x-rays have proven as a fundamental tool to investigate solid-state physics. With the advent of synchrotron radiation intense and collimated x-ray beams are routinely available to scientist studying not only physics, but also chemistry and biology. However, due to their electromagnetic nature, x-rays are well suited to study also magnetic materials.

In this talk I will give an overview of some of the possibilities offered by synchrotron x-ray radiation to study magnetic properties in solid-state physics using techniques as X-ray Magnetic Circular Dichroism (XMCD), X-ray Magnetic Diffraction (XMD) and recent development in imaging of magnetic moment configurations in bulk sample and nanostructures with magnetic tomography [1-3].
