Electric field modulation of magnetic properties has been attracting attentions because of its fundamental importance for material science as well as potential applications for magnetic recording media. It has been reported that an electric field applied to a ferromagnetic metal can change the magnetic anisotropy and the Curie temperature. Additionally, proximity-induced ferromagnetism in Pd can be controlled by an electric field. We report an electric field modulation of the ferromagnetism in Pt by X-ray magnetic circular dichroism (XMCD) and absorption spectroscopy (XAS) to unveil the microscopic mechanism. In the presentation, we will discuss detail mechanisms by relating those modulations to changes in the electronic structure.
