Cover Story: Iron substitution within nickel hydroxide nanosheets substantially affects structure and magnetization. As the Fe substitution ratio increases, both the nanocrystallite shape anisotropy and the magnetic coercivity increase in unison. More importantly, at a low Fe substitution ratio of 5 atomic %, the material is ferromagnetic but 10% and 20% Fe-substituted samples exhibit ferrimagnetic ordering. Additionally, for the higher Fe %, we observe magnetization reversal which is likely due to the larger magnetocrystalline anisotropy. This work furthers understanding of the unique interconnections between structure and magnetization of nanomaterials and can lead to improved materials for batteries, catalysts, electronics, gas sensing, and spintronics.
