Research Interests:

• I have intensively studied the interface magnetism of magnetic thin films by using x-ray absorption techniques (XAFS, EXAFS, and XMCD) using synchrotron radiation at Photon Factory and SPring-8 in Japan.

Abstract:

Interfacial behaviours and properties play critical roles in determining the practical parameters of thin film-based functional materials. Over the years, extensive interface investigations have been carried out with various techniques. Soft x-ray spectroscopy presents shallow penetration depth so to show high surface sensitivity and characterize the interfacial behaviour with elemental selectivity. In this talk, I present recent studies of the synchrotron-based soft x-ray spectroscopy of the interface in the magnetic thin films. We focus on the depth-resolved soft x-ray absorption spectroscopy that enables the layer-resolved investigation of the magnetic state of the magnetic multilayers, and further application to the operando measurement is presented
