From Magnetic Nanoparticles to Superstructures: A Bottom-Up Strategy for Enhanced Material Functionality

This project aims to advance the understanding of self-assembled magnetic nanoparticle (NP) arrays through a combination of chemical and physical bottom-up strategies.

The formation of ordered structures, known as superlattices, holds significant promise for tailoring materials with customized magnetic properties.

The challenge lies in comprehensively elucidating the synthesis, assembly dynamics, and collective magnetic behavior of these NP arrays.

To address this challenge, a novel template-free method has been developed, allowing for the precise control of magnetic NP assembly on various surfaces.

By integrating chemical synthesis techniques to produce oxide NPs and physical methods to generate metal NPs, the project aims to fabricate hybrid bimagnetic composites with tailored properties.

Through systematic investigations, the project seeks to unravel the interplay between composition, shape, and magnetic anisotropy of NPs within mesoscale arrangements.

This will enable the design of materials with enhanced magnetic characteristics for applications spanning biomedical devices, permanent magnets, electronics, and magnetoresistive devices.

The project is organized into two main aims: (1) synthesis and assembly of magnetic NPs and (2) assembly of hybrid oxide/metal NP composites into superstructures.

Through collaborative efforts and interdisciplinary approaches, the project seeks to achieve a comprehensive understanding of self-assembled bimagnetic NP arrays.
