# Manifestation of dipole-induced disorder in self-assembly of ferroelectric and ferromagnetic nanocubes

## TL;DR

This study investigates how dipole-induced disorder affects the self-assembly of ferroelectric and ferromagnetic nanocubes, revealing that dipoles significantly influence their structural correlations during densification.

## Contribution

It provides the first detailed simulation and microstructural analysis of dipolar nanocube self-assembly, highlighting the role of dipoles in structural organization.

## Key findings

- Dipoles strongly affect positional correlations.
- Dipolar interactions influence orientational order.
- Structural correlations are sensitive to dipole presence.

## Abstract

The colloidal processing of nearly monodisperse and highly crystalline single-domain ferroelectric or ferromagnetic nanocubes is a promising route to produce superlattice structures for integration into next-generation devices, whereas controlling the local behaviour of nanocrystals is imperative for fabricating highly-ordered assemblies. The current picture of nanoscale polarization in individual nanocrystals suggests a potential presence of a significant dipolar interaction, but its role in the condensation of nanocubes is unknown. We simulate the self-assembly of colloidal dipolar nanocubes under osmotic compression and perform the microstructural characterization of their densified ensembles. Our results indicate that the long-range positional and orientational correlations of perovskite nanocubes are highly sensitive to the presence of dipoles.
