INMA Impulso: Takafumi Miyanaga
INMA Impulso Seminar: Local structure and dynamics of functional materials studied by XAFS
On Thursday 20 July will be held a new seminar INMA – Impulse, a series of conferences that seeks to bring the most cutting-edge research to society.
On this occasion we will have Prof. Takafumi Miyanaga of Hirosaki University, Japan, who will give a lecture entitled: “Local structure and dynamics of functional materials studied by XAFS”.
The session will take place on Thursday 20 July at 12:00 in the Sala de Grados of the Faculty of Science of the University of Zaragoza.
Summary of the lecture: Prof. Takafumi Miyanaga is a Professor in the Department of Mathematics and Physics at Hirosaki University in Japan. He has exhaustive experience in applications of X-rays, particularly the X-ray absorption fine structure (XAFS) technique, to analyze the local structure and dynamics of functional materials: (1) structure phase transition in ferroelectric perovskites (PbTiO3) and magnetic FeRhPd alloys; (2) nano-scaled fluctuations related to their magnetic properties in Ni–Mn alloys and Fe/Cr thin films; and (3) the Debye–Waller factors related to the chemical reactivity for ligand exchange reaction and catalysis in polyanions. These studies show that the local structure and dynamics are related to the characteristic function of the materials.
