Structural and Magnetic Properties of Manganese Zinc Ferrite Nanoparticles Exhibiting Superparamagnetism

Abstract

This thesis report delves into the intriguing realm of nanoscale magnetic materials by investigating the superparamagnetic behavior of MnZn ferrite nanoparticles. These nanoparticles have garnered significant attention due to their unique magnetic properties, which stem from their small size and high surface-to-volume ratio. The study begins with a comprehensive review of the existing literature on superparamagnetism. The obtained results reveal the Superparamagnetic nature of the MnZn ferrite nanoparticles, focusing on their response to external magnetic fields and their potential applications in various fields. The findings suggest that the nanoparticles' magnetic behavior transitions from superparamagnetic to blocked as the temperature decreases, leading to potential applications in data storage, biomedical imaging, and targeted drug delivery. The implications of these findings extend beyond the realm of fundamental research, opening doors for technological advancements. By understanding and harnessing the superparamagnetic behavior of MnZn ferrite nanoparticles, researchers can design novel devices with enhanced functionalities. However, challenges related to size distribution, stability, and surface modification need to be addressed to fully exploit the potential of these nanoparticles.
