Full Heusler compounds with Cobalt as a primary element show anomalous transport properties owing to the Weyl fermions and broken time-reversal symmetry. We present here the study of anomalous Hall effect (AHE) in Co2FeGe Heusler compound. The experiment reveals anomalous Hall conductivity (AHC) ∼ 100S/cm at room temperature with an intrinsic contribution of ∼ 78S/cm . The analysis of anomalous Hall resistivity suggests the scattering independent intrinsic mechanism dominates the overall…

Anomalous Hall effect in the half-metallic Heusler compound Co2TiX ( X=Si , Ge)
Though Weyl fermions have recently been observed in several materials with broken inversion symmetry, there are very few examples of such systems with broken time reversal symmetry. Various
Pressure-tunable large anomalous Hall effect of the ferromagnetic kagome-lattice Weyl semimetal Co3Sn2S2
We investigate the pressure evolution of the anomalous Hall effect in magnetic topological semimetal Co3Sn2S2 in diamond anvil cells with pressures up to 44.9-50.9 GPa. No evident trace of structural
Giant anomalous Hall and Nernst effect in magnetic cubic Heusler compounds
The interplay of magnetism and topology opens up the possibility for exotic linear response effects, such as the anomalous Hall effect and the anomalous Nernst effect, which can be strongly enhanced
Anomalous Hall effect derived from multiple Weyl nodes in high-mobility EuTiO3 films
The theoretical calculation indicates that the change of Zeeman field in the process of canting the magnetic moments causes the type II Weyl nodes in the conduction band to move, resulting in a peculiar magnetic field dependence of the AHE; this is revealed by the high-quality films with a long scattering lifetime of conduction electrons.
Weak localization and small anomalous Hall conductivity in ferromagnetic Weyl semimetal Co2TiGe
Weak localization and small anomalous Hall conductivity in half-metallic Co2TiGe thin films grown by molecular beam epitaxy are reported and the longitudinal resistivity shows semimetallic behavior.
Giant anomalous Hall angle in a half-metallic magnetic Weyl semimetal
Magnetic Weyl semimetals (WSMs) with time reversal symmetry breaking exhibit Weyl nodes that act as monopoles of Berry curvature and are thus expected to generate a large intrinsic anomalous Hall

Large intrinsic AHE with linear dependence on magnetization in a half-metallic ferromagnet Co3Sn2S2 single crystal with Kagome lattice of Co atoms, arising dominantly from the Weyl fermions is reported.
Thickness dependence of the anomalous Hall effect in thin films of the topological semimetal Co2MnGa
Topological magnetic semimetals promise large Berry curvature through the distribution of the topological Weyl nodes or nodal lines and further novel physics with exotic transport phenomena. We
Giant anomalous Hall effect in a ferromagnetic Kagomé-lattice semimetal
Electrical transport measurements reveal that Co3Sn2S2 is probably a magnetic Weyl semimetal, and hosts the highest simultaneous anomalous Hall conductivity and anomalies angle, driven by the strong Berry curvature near the Weyl points.
