Effect of Distributed Particle Magnetic Moments on the Magnetization of NiO Nanoparticles

TL;DR

This paper investigates how considering the distribution of magnetic moments in NiO nanoparticles clarifies previous anomalous magnetization observations, emphasizing the importance of this factor in accurate analysis.

Contribution

It introduces a comprehensive analysis method that accounts for magnetic moment distribution, resolving inconsistencies in prior experimental results on NiO nanoparticles.

Findings

Distribution of magnetic moments explains anomalous magnetization behaviors.

Ignoring magnetic moment distribution leads to misinterpretation of data.

Proper analysis aligns experimental results with theoretical expectations.

Abstract

Magnetization of nanoparticles of NiO are measured and analyzed taking into account a distribution in particle magnetic moment. We find that disregarding this distribution in the analysis is the reason for the many anomalous observations reported on this system in the literature.
