To harvest the unique properties offered by 2D HSs, creation of well-defined heterointerfaces on a large scale is a prerequisite, where the chemistry and nature of heterointerfaces define the targeted applications.

Temperature plays a vital role in the hydrothermal synthesis of the nanoparticles. Herein, we have provided a very detailed spin dynamic investigation on the varying size Fe ₃ O ₄ nanoparticles using FMR technique.
