Magnetic materials play a major role in the current energy and societal transitions. However, the development of sustainable yet performant materials, without critical elements such as rare-earths (RE), remains a challenge. The bottom-up approach opens great potentiality for the rational design of efficient RE free magnetic materials, by the fine tuning of the intrinsic properties of individual particles, through their anisotropy, and their controlled assembly resulting in optimized collective properties.
We will present the chemical synthesis of bimetallic nanoparticles following either organometallic approaches or polyol processes. Their applications as catalytic agents magnetically heated or as building blocks for magnetic materials using the magnetophoresis-driven assembly process will be discussed.
