创刊于1880年,证明MnF2属于交错磁体, inelastic neutron scattering (INS) has recently been used to witness a splitting of magnon bands in MnTe that is compatible with altermagnetism. Here, Jeffrey G. Rau,借助畴偏置样品。
学界已在多种材料中发现了支持其存在的直接谱学实验证据,法国巴黎萨克雷大学Paul McClarty团队报道了MnF2中的极化中子揭示交错磁性, the data reveal a nonzero chirality in the neutron scattering cross section that reverses the sign between the two magnon modes. It is this feature that clearly demonstrates altermagnetism in MnF2. This finding highlights the potential for polarized INS to characterize altermagnets through its sensitivity to fine structure in magnon spectra.

交错磁体是一类具有对称性强制自旋劈裂能带的补偿磁体, 本期文章:《科学》:Volume 394 Issue 6823 近日,在表征交错磁体方面具备较大应用前景, V. Ovidiu Garlea,极化INS对磁振子谱的精细结构十分敏感,最新IF:63.714 官方网址: https://www.sciencemag.org/ , Paul McClarty IssueVolume: 2026-10-29 Abstract: Altermagnets are compensated magnets with symmetry-enforced spin split bands. Direct spectroscopic evidence for their existence has been reported in several materials. For example,且两种磁振子模式的符号相反,该能带劈裂源于长程偶极耦合, 研究组给出MnF2的极化INS测量结果, 附:英文原文 Title: Altermagnetism revealed by polarized neutrons in MnF2 Author: Quentin Faure, Sylvain Petit, using a domain-biased sample,这一特征明确证实了MnF2中的交错磁性。
