摘要

磁性材料的磁电特性可以通过外部磁场、温度和压力来改变,因此在现代技术应用中越来越受到关注。为了在高级应用中利用磁性固体,必须以原子级精度理解磁性材料中温度相关自旋有序(反铁磁,铁磁和顺磁相)的准确描述和细节。低频振动动力学可以用来研究磁性结构的基态结构-性质关系,如图所示。

Determining the Magnetic Configuration of Crystalline Solids with Terahertz Spectroscopy
Magnetic materials are increasingly garnering attention for modern technological applications because of their magnetoelectric properties, which can be modified by external magnetic fields, temperature, and pressure. To utilize magnetic solids in advanced applications, accurate descriptions and details about temperature-dependent spin ordering (antiferromagnetic, ferromagnetic and paramagnetic phases) within the magnetic materials must be understood with atomic-level precision. Low-frequency vibrational dynamics can be used to investigate ground state structure-property relationship of magnetic structures, as demonstrated here for FePO4.
