Coherent spin dynamics of nanomolecules and magnetic nanoclusters

TL;DR

This paper analyzes the coherent spin dynamics of nanomolecules and nanoclusters, considering their single-domain magnetic properties and collective behaviors, and compares different theoretical approaches to understand the main mechanisms influencing their spin motion.

Contribution

It provides a comparative analysis of various approaches to model spin dynamics in nanomolecules and nanoclusters, highlighting the main mechanisms affecting their coherence and collective behavior.

Findings

Nanomolecules and nanoclusters behave as single-domain magnets with large total spins.

Coherent spin motion occurs both within individual nanoclusters and among ensembles.

Different theoretical models reveal key mechanisms influencing spin coherence.

Abstract

Spin dynamics of nanomolecules and nanoclusters are analyzed. The nanosizes of these objects make it possible to consider them as single-domain magnets with a large total spin, where the motion of the spins of all atoms, composing a nanocluster, occurs in a coherent way. Another meaning of coherence in spin dynamics is the coherent spin motion of several nanomolecules or nanoclusters. Different approaches for treating spin dynamics are compared and the main mechanisms influencing the spin motion are studied. Spin dynamics of separate magnetic nanomolecules and nanoclusters are investigated, as well as the spin dynamics of the ensembles of these nano-objects.
