Giant Exfoliation Induced Magnetic Coercivity in FeGaTe
Lingrui Mei, PeiYu Cai, Sang-Eon Lee +6
Permanent magnets with strong anisotropy and high coercivity underpin modern information and energy technologies, yet rare-earth-free alternatives remain limited. Here, we show tha…
Topological Hall Effect in Antiferromagnetic Co doped FeGaTe
Shyam Raj Karullithodi, Yeonkyu Lee, Vadym Kulichenko +8
FeGaTe is van der Waals (vdW) ferromagnet with a Curie temperature ranging from 350 K to 380 K, followed upon cooling by a ferrimagnetic transition near room temperat…
Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet
Sheikh Rubaiat Ul Haque, Martin J. Cross, Sangeeta Rajpurohit +19
Strong-field terahertz (THz) excitations enable dynamic control over electronic, lattice and symmetry degrees of freedom in quantum materials. Here, we uncover pronounced terahertz…
Disorder driven crossover between anomalous Hall regimes in FeGaTe
Sang-Eon Lee, Minkyu Park, W. Kice Brown +8
The large anomalous Hall conductivity (AHC) of the Fe(Ge,Ga)Te compounds has attracted considerable attention. Here, we expose the intrinsic nature of AHC in FeGaTe…
Local Inversion Symmetry Breaking and Thermodynamic Evidence for Ferrimagnetism in Fe3GaTe2
Sang-Eon Lee, Yue Li, Yeonkyu Lee +19
The layered compound Fe3GaTe2 is attracting attention due to its high Curie temperature, low dimensionality, and the presence of topological spin textures above room temperature, m…
Type-II Weyl nodes, flat bands, and evidence for a topological Hall-effect in the new ferromagnet FeCrTe
Shyam Raj Karullithodi, Vadym Kulichenko, Mario A. Plata +5
The interplay between linearly dispersing or Dirac-like, and flat electronic bands, for instance, in the kagome ferromagnets, has attracted attention due to a possible interplay be…
