4.1.1 Introduction

While the organic–inorganic hybrid perovskites such as CH₃NH₃PbX₃ (where X stands for halide) have achieved rapid progress in optoelectronic device applications that include solar cells [1–3] and light‐emitting diodes (LEDs) [4, 5], the community has realized that another research topic in this field is interesting as well, namely, spin physics and spin‐related devices of hybrid perovskites [6]. In this regard, it was not clear why the Pb atoms having large spin–orbit coupling ...
