The crystal is formed by small volume elements magnetized to saturation as a result of interactions between neighbouring spins that tend to align in parallel. These volume elements are called magnetic domains, the adjacent domains being separated by transition zones called block walls. The film aims to study the dynamics of these walls, i.e. their movements when the crystal is subjected to a magnetic field. The experimental study itself uses a metallographic microscope. The sample,…

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
