Switching Anomalous Hall and Nernst Responses by Nonmagnetic N Occupation at Fixed Noncoplanar Mn Antiferromagnetic Order
Xin Liu, Jiyuan Xu, Li Ma +4
Nonmagnetic atomic occupation can control anomalous transverse transport by modifying magnetic symmetry without changing the underlying magnetic order. We demonstrate this effect u…
Bond-selective modulation of scalar spin chirality in strained Mn4N
Xin Liu, Li Ma, Mingyue Zhao +10
Scalar spin chirality (SSC) underlies a variety of Berry-phase-driven transport phenomena in noncoplanar magnets. Mn4N is a unique ferrimagnetic system in which both collinear and…
Giant Full-Space Anomalous Hall Effect Induced by Non-Coplanar Spin State in Mn-Rich Mn3Sn
Yiming Liu, Xin Liu, Jiayao Zhu +6
Antiferromagnets are promising candidates for next-generation spintronic devices owing to their negligible stray fields and ultrafast spin dynamics. The noncollinear antiferromagne…
Nitrogen-Vacancy Engineering for Controlled Phase Transitions in CrN(111) Epitaxial Films
XiaoXu Zhang, Yang Li, Yu Shang +6
The phase transition in CrN epitaxial films is substantially suppressed by epitaxial constraint. Here, we propose that nitrogen (N) vacancies can be taken as a knob to regulate the…
Flexible manipulation of chiral spin state by chemical bond in Mn triangular lattice magnet
Jiyuan Xu, Xin Liu, Li Ma +4
This study investigates the influence of chemical bonds on the magnetic structure of materials, a less explored area compared to their effect on crystal stability. By analyzing the…
Extrinsic suppression of anomalous Hall effect in Fe-rich kagome magnet Fe3Sn
Muhua Liu, Li Ma, Guoke Li +3
In Fe-based kagome magnets, Fe3Sn has been predicted to have the largest intrinsic anomalous Hall conductivity (AHC) and the highest Curie temperature TC = 743 K. However, the curr…
Large topological Hall effect arising from spin reorientation in kagome magnet Fe3Ge
Zixuan Zhang, Mingyue Zhao, Li Ma +4
Materials systems with spin chirality can provide ultra-high-density, ultra-fast, and ultralow-power information carriers for digital transformation. These material systems include…
Effect of residual strain on non-collinear antiferromagnetic structure in Weyl semimetal Mn3Sn
J. J. Deng, J. Li, Y. Wang +9
The non-collinear antiferromagnetic (AFM) structure makes Mn3Sn exhibit exotic properties. At present, it has been found that both the hydrostatic pressure and the strain introduce…
Coexistence of spin frustration and spin unfrustration induced spontaneous exchange bias in Heusler alloys
J. Li, X. Wang, J. J. Deng +9
The mechanism of spontaneous exchange bias (SEB) and the dominant factor of its blocking temperature are still unclear in Heusler alloys. Here, the related investigations are perfo…
Dynamic magnetic-transformation-induced exchange bias in (Fe2O3)0.1-(FeTiO3)0.9
P. Song, L. Ma, G. K. Li +11
Up to now, for the conventional exchange bias (EB) systems there has been one pinning phase and one pinned phase, and the pinning and pinned phases are inherent to the material and…
Absence of Metallic Behavior in Epitaxial NiCo2O4 Thin Films: Role of Microstructural Disorder
Congmian Zhen, XiaoZhe Zhang, Wengang Wei +6
Despite the low resistivity (~ 1 mohm cm), the metallic electrical transport has not been commonly observed in the inverse spinel NiCo2O4, except in certain epitaxial thin films. P…
