ArXiv

Analysis

This paper investigates the energy landscape of magnetic materials, specifically focusing on phase transitions and the influence of chiral magnetic fields. It uses a variational approach to analyze the Landau-Lifshitz energy, a fundamental model in micromagnetics. The study's significance lies in its ability to predict and understand the behavior of magnetic materials, which is crucial for advancements in data storage, spintronics, and other related fields. The paper's focus on the Bogomol'nyi regime and the determination of minimal energy for different topological degrees provides valuable insights into the stability and dynamics of magnetic structures like skyrmions.

Ligand Shift Impact on Heisenberg Exchange and Spin Dynamics

Published:Dec 26, 2025 18:34
1 min read
ArXiv

Analysis

This paper explores a refinement to the understanding of the Heisenberg exchange interaction, a fundamental force in magnetism. It proposes that the position of nonmagnetic ions (ligands) between magnetic ions can influence the symmetric Heisenberg exchange, leading to new terms in the energy density and impacting spin wave behavior. This has implications for understanding and modeling magnetic materials, particularly antiferromagnets and ferrimagnets, and could be relevant for spintronics applications.
Reference

“The paper suggests that the ligand shift can give contribution in the constant of the symmetric Heisenberg interaction in antiferromagnetic or ferrimagnetic materials.”
