· CrI2

Chromium iodide (CrI₂) is a layered transition metal halide compound that exists as a crystalline solid with magnetic properties. This material is primarily of research and developmental interest rather than established in mainstream engineering, representing an emerging class of two-dimensional materials being investigated for advanced electronics and spintronics applications. The weak interlayer bonding characteristic of this layered structure makes it a candidate for exfoliation into thin sheets, positioning it within the broader family of van der Waals materials being explored for next-generation devices where layer-dependent properties are advantageous.
