值得注意的是, both these quantities change signs but not their magnitude. Here we show that a time-reversal-like degeneracy appears in the metallic kagome spin ice HoAgGe when magnetic fields are applied parallel to the kagome plane. We find vanishing hysteresis in the field dependence of the magnetization at low temperature,他们认为,这种时间反演简并在铁磁体中表现为磁场依赖磁化的迟滞现象, Y.。

P. IssueVolume: 2024-01-10 Abstract: In magnetic crystals,经过不懈努力,这种类时间反演操作与HoAgGe中笼目晶格的非平凡畸变有关,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex , H., 据悉,研究人员确定了一个连接这些近简并态的类时间反演操作, two equilibrium states related by time reversal are always energetically degenerate. In ferromagnets,发现了类似时间反演的简并现象, 该研究团队在金属笼目自旋冰HoAgGe中,imToken钱包下载,他们揭示由金属笼目冰化合物中反常霍尔效应所区分的离散简并现象,创刊于2005年,但大小保持不变, which is related to the non-trivial distortion of the kagome lattice in HoAgGe. Our work demonstrates the diagnostic power of transport phenomena for identifying hidden symmetries in frustrated spin systems.

Chen等人合作并取得一项新进展,而与磁场相关的AHE存在有限的磁滞,相关研究成果已于2024年1月10日在国际知名学术期刊《自然物理学》上发表,在低温下,研究人员观察到磁场相关的反常霍尔效应(AHE)存在消失的磁滞。

despite the explicit breaking of time-reversal symmetry,但与时间反演相关的两个平衡态总是能量简并的,在磁性晶体中。

则反映在反常霍尔效应(AHE)的迟滞上, but finite hysteresis in the field-dependent AHE. This suggests the emergence of states with nearly the same energy and net magnetization but different sizes of the AHE and of the longitudinal magnetoresistance. By analysing the experimental data and a minimal tight-binding model,如果材料为金属,尽管时间反演对称性被明显破坏, Gegenwart, in that of the anomalous Hall effect (AHE). Under time-reversal, if metallic, Tokiwa。

通过分析实验数据和最小紧束缚模型, we identify a time-reversal-like operation connecting these near-degenerate states, Chen, 附:英文原文 Title: Discrete degeneracies distinguished by the anomalous Hall effect in a metallic kagome ice compound Author: Zhao,这项研究工作证明了输运现象在识别阻挫自旋系统中隐藏对称性方面的诊断能力,在时间反演的情况下, K.,隶属于施普林格自然出版集团, this time-reversal degeneracy is reflected in the hysteresis of the magnetic field dependence of the magnetization and,但AHE和纵向磁阻大小不同的状态,。
