What is Magnon and Phonon Excitations in Nanosized NiO about?

The study investigates magnon and phonon excitations in nanosized nickel oxide (NiO) using Raman spectroscopy, revealing new spectral features and the effects of particle size on magnetic ordering. Key findings include the presence of a new band at ~200 cm-1 and TO-LO splitting in the phonon modes, indicating complex magnetic behavior in nanocrystalline NiO. The research highlights the differences in vibrational properties between bulk and nanosized NiO, emphasizing the influence of finite-size effects on m
