43. Combined experimental and ab-initio studies of Ca3Ti2O7 local structure

Prof. Lucy Vitoria Credidio Assali (Instituto de Fisica da Universidade de São Paulo)

Abstract

Techniques for studying short-range interactions have been successfully used to evaluate local parameters of crystals with high precision. In particular, experiments using perturbed angular correlation (PAC) spectroscopy were able to track the high-temperature phase transitions of hybrid improper ferroelectrics. Here, we continued such works by combining PAC spectroscopy with...
