FeI2 is a metal halide compound composed of iron and iodine that has a layered crystal structure with weak interlayer interactions held together by van der Waals forces. This magnetic material exhibits antiferromagnetic ordering, where adjacent spins in the lattice are oriented in opposite directions, leading to a net magnetization of zero. FeI2 has garnered attention due to its potential use in magnetic devices and in the synthesis of other materials. Moreover, it presents remarkable properties, such as high resistivity and low thermal conductivity, making it a promising candidate for use in thermoelectric applications.
