Simulation of colloidal chain movements under a magnetic field

TL;DR

This paper simulates the behavior of colloidal chains under magnetic fields using lattice models, revealing how dipole interactions influence chain alignment.

Contribution

It introduces a simulation approach combining the slithering-snake algorithm and Ising model to study magnetic field effects on colloidal chains.

Findings

Chains align with the magnetic field due to dipole interactions

Dipole alignment depends on field strength and chain length

Simulation captures the collective behavior of colloidal chains

Abstract

Short colloidal chains are simulated by the slithering-snake-algorithm on a simple cubic lattice. The dipole character of the colloidal particles leads to a long range dipole-dipole interaction. The solvent is simulated by the nearest neighbor Ising model. The aligning of the dipoles under a magnetic field gives rise to the chains to align on their part with the field direction.
