报告摘要：

Spin fluctuations are of fundamental importance in magnetism, not only determining thermodynamic properties of magnets, but also finding their roles in some of the most attracting topics in modern condensed matter physics, such as Fe based superconductivity and spintronics. Time dependent density functional perturbation theory (TDDFPT) provides a parameter-free tool to study spin fluctuations, without involving approximations beyond those already been made in practical density functional theory calculations. I will talk about our implementation of TDDFPT for spin fluctuations using plane-waves and pseudopotentials approach based on Quantum Espresso. I will then show our benchmarking results on bcc Fe, fcc Ni, bcc Cr.
