A stable and strongly ferromagnetic Fe₁₇O₁₀ cluster with an accordion-like structure

L. Geng, X. Yu, et al.

This research dives into the gas-phase reactions of iron clusters with oxygen, revealing that while larger clusters react with O₂, smaller ones do not. Notably, Fe₁₇O₁₀ showcases remarkable stability and a unique accordion-like structure, along with strong ferromagnetic properties, suggesting exciting applications in high-density storage and spintronics. Conducted by Lijun Geng, Xiaohu Yu, and Zhixun Luo.

Abstract
This research investigates the gas-phase reactions of iron clusters (Feₙ⁻, n=7–31) with oxygen. The study finds that larger clusters (n ≥ 15) react with O₂, while smaller ones are unreactive. Fe₁₇O₁₀ shows prominent abundance, indicating its distinct stability. DFT calculations reveal its accordion-like structure and strongly ferromagnetic nature (56 µB), a significant finding for its potential applications in high-density storage or spintronics.
