Chemical disorder as engineering tool for spin-polarizationin Mn3Ga-based Heusler systems
Stanislav Chadov, Sunil Wilfred D'Souza, Lukas Wollmann +3
Our study highlights spin-polarization mechanisms in metals, by focusing on the mobilities of conducting electrons with different spins instead of their quantities. Here, we engine…
Quantum Anomalous Hall Effect in Magnetic Insulator Heterostructure
Gang Xu, Jing Wang, Claudia Felser +2
Based on ab initio calculations, we predict that a monolayer of Cr-doped (Bi,Sb)2Te3 and GdI2 heterostructure is a quantum anomalous Hall insulator with a non-trivial band gap up t…
Non-collinear Antiferromagnets and the Anomalous Hall Effect
Juergen Kübler, Claudia Felser
The anomalous Hall effect is investigated theoretically by means of density functional calculations for the non-collinear antiferromagnetic order of the hexagonal compounds MnG…
Guidelines for understanding cubic manganese-rich Heusler compounds
Lukas Wollmann, Stanislav Chadov, Jürgen Kübler +1
Manganese-rich Heusler compounds are attracting much interest in the context of spin transfer torque and rare-earth free hard magnets. Here we give a comprehensive overview of the…
On the superconductivity of TiNCl and ZrNCl: A local bonding perspective
Lukas Muechler, Leslie M. Schoop, Claudia Felser
We analyze the superconductors TiNCl and ZrNCl from a local bonding perspective. Although TiNCl crystallizes in an orthorhombic structure and ZrNCl crystallizes in a hexagonal stru…
Paramagnetic to ferromagnetic phase transition in lightly Fe-doped CrB
Leslie M. Schoop, Max Hirschberger, Jing Tao +3
CrB displays temperature independent paramagnetism. We induce ferromagnetism by replacing less than of the Cr atoms by Fe. By the lowest Fe doping level made, Curie-Wei…
