Electric Polarization and Magnetic Properties of (NH $_{4}$ ) $_{1 - x}$ K $_{x}$ I (x = 0.05-0.17)

Yi Yang Xu, Lei Meng, Miao Miao Zhao +2

While all of the polymorphs of pure NH $_{4}$ I and KI are non-polar, we identify that (NH $_{4}$ ) $_{0.95}$ K $_{0.05}$ I is ferroelectric and (NH $_{4}$ ) $_{0.87}$ K $_{0.13}$ I and (NH $_{4}$ )$_{0.8…

Magnetic interactions based on proton orbital motion in CH $_{3}$ NH $_{3}$ PbI $_{3}$ and CH $_{3}$ NH $_{3}$ PbBr $_{3}$

Lei Meng, Miao Miao Zhao, Yi Yang Xu +5

The microscopic origin of the remarkable optoelectronic properties of one of the most studied contemporary materials remains unclear. Here, we identify the existence of magnetic in…
