The physics of magnetization

TL;DR

This paper discusses how magnetization results from structural rearrangements in materials, driven by nucleation and growth mechanisms, aligning with recent experimental observations about spin orientation.

Contribution

It introduces a structural perspective on magnetization, emphasizing the role of crystal rearrangement via nucleation and growth, which is a novel approach compared to traditional spin-based models.

Findings

Magnetization involves crystal structure rearrangement.

Experimental observations support the structural mechanism.

Nucleation-and-growth is key to understanding magnetization.

Abstract

Experimental observations recently reported in Nature are in accord with the concept that spin orientation is a permanent feature of the spin carrier. It follows that magnetization is realized by rearrangement of the crystal structure. The rearrangement occurs by the general contact nucleation-and-growth mechanism.
