Au4Mn, a localized ferromagnet with strong spin-orbit coupling, long-range ferromagnetic exchange and high Curie temperature
Yangkun He, Zsolt Gercsi, Rui Zhang +8
Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal…
Rare-earth-free noncollinear metallic ferrimagnets Mn4-xZxN with compensation at room temperature
Rui Zhang, Yangkun He, Daniel Fruchart +2
Compensated ferrimagnets, like antiferromagnets, show no net magnetization but their transport and magneto-optic properties resemble those of ferromagnets, thereby creating opportu…
Antiskyrmions and their electrical footprint in crystalline mesoscale structures of MnPtSn
Moritz Winter, Francisco J. T. Goncalves, Ivan Soldatov +17
Skyrmionic materials hold the potential for future information technologies, such as racetrack memories. Key to that advancement are systems that exhibit high tunability and scalab…
Large topological Hall effect in an easy-cone ferromagnet (Cr0.9B0.1)Te
Yangkun He, Johannes Kroder, Jacob Gayles +5
The Berry phase understanding of electronic properties has attracted special interest in condensed matter physics, leading to phenomena such as the anomalous Hall effect and the to…
Topological Hall effect arising from the mesoscopic and microscopic non-coplanar magnetic structure in MnBi
Yangkun He, Sebastian Schneider, Toni Helm +9
The topological Hall effect (THE), induced by the Berry curvature, which originates from non-zero scalar spin chirality, is an important feature for mesoscopic topological structur…
New highly-anisotropic Rh-based Heusler compound for magnetic recording
Yangkun He, Gerhard H. Fecher, Chenguang Fu +18
The development of high-density magnetic recording media is limited by the superparamagnetism in very small ferromagnetic crystals. Hard magnetic materials with strong perpendicula…
Phase transition in the magnetocrystalline anisotropy of tetragonal Heusler alloys: RhSb, Fe, Co
Gerhard H. Fecher, Yankun He, Claudia Felser
This work reports on first principles calculations of the electronic and magnetic structure of tetragonal Heusler compounds with the composition RhFeCoSb ($0\leq…
