Observation of spin dynamics of ferromagnets and antiferromagnets using the time structure of X-rays

抄録

In recent years, magnetization control using light has attracted much attention with the goal of realizing next-generation ultrafast magnetic information devices. This paper introduces the results of a study that observed the spin dynamics of a magnetic material after irradiating it with an ultrashort pulse laser. We report how combining laboratory lasers and synchrotron radiation at large facilities revealed the ultrafast spin dynamics.
