Simulating the dynamic susceptibility of magnetic colloidal polymers / Simulacija dinamičke susceptibilnosti magnetnih koloidnih polimera

Magnetic Colloidal Polymers (MCPs) are polymer-like mesostructures composed of permanently crosslinked magnetic nanoparticles (MNPs), encompassing systems with varied magnetic content, solvent affinity, and composition profiles. Similarly to chemical polymers, their self-assembly into superstructures can be controlled through solvent selectivity and backbone composition. The interplay of solvophilic, solvophobic, and magnetic interactions gives rise to complex self-assembly behaviour that can be manipulated with external magnetic fields, offering dynamic control and high spatial resolution [1]. Studying dynamic susceptibility in MCP-based fluids requires advances in both simulation methodology and large-scale modelling. Dynamic susceptibility is a collective property of MCP-based fluids that characterises their dynamics, i.e. characteristic magnetic relaxation times, and is a key measurable quantity for the development of MCP-based magnetic fluids for applications such as magnetic hyperthermia [2].
