Growth mechanism and magnon excitation in NiO nanowalls

Abstract The nanosized effects of short-range multimagnon excitation behavior and short-circuit diffusion in Horse Fly Masks NiO nanowalls synthesized using the Ni grid thermal treatment method were observed.The energy dispersive spectroscopy mapping technique was used to characterize the growth mechanism, and confocal Raman scattering was used to probe the antiferromagnetic exchange energy J 2 between next-nearest-neighboring Ni ions in NiO nanowalls at various growth temperatures below the Neel temperature.This study shows that short spin correlation leads to an exponential dependence of the growth temperatures and the existence of nickel vacancies during the magnon excitation.Four-magnon configurations were determined from the scattering factor, revealing a lowest ENERGIN UNFLAVOURED state and monotonic change with the growth temperature.
