Optimization of reactively sputtered Mn3GaN films based on resistivity measurements
Christoph Sürgers, Gerda Fischer, Sihao Deng +2
Mn-based nitrides with antiperovskite structures have several properties that can be utilised for antiferromagnetic spintronics. Their magnetic properties depend on the structural…
Magnetotransport in ferromagnetic Mn5Ge3, Mn5Ge3C0.8, and Mn5Si3C0.8 thin films
Christoph Sürgers, Gerda Fischer, Patrick Winkel +1
The electrical resistivity, anisotropic magnetoresistance (AMR), and anomalous Hall effect of ferromagnetic Mn5Ge3, Mn5Ge3C0.8, and Mn5Si3C0.8 thin films has been investigated. The…
Switching of a large anomalous Hall effect between metamagnetic phases of a non-collinear antiferromagnet
Christoph Sürgers, Thomas Wolf, Peter Adelmann +3
The anomalous Hall effect (AHE), which in long-range ordered ferromagnets appears as a voltage transverse to the current and usually is proportional to the magnetization, often is…
Phase transitions associated with magnetic-field induced topological orbital momenta in a non-collinear antiferromagnet
Sihao Deng, Olena Gomonay, Jie Chen +12
Resistivity measurements are widely exploited to uncover electronic excitations and phase transitions in metallic solids. While single crystals are preferably studied to explore cr…
Lateral Mn5Ge3 spin-valve in contact with a high-mobility Ge two-dimensional hole gas
David WeiÃhaupt, Christoph Sürgers, Dominik Bloos +8
Ge two-dimensional hole gases in strained modulation-doped quantum-wells represent a promising material platform for future spintronic applications due to their excellent spin tran…
Anomalous Nernst effect in the noncollinear antiferromagnet MnSi
Christoph Sürgers, Gerda Fischer, Warlley H. Campos +6
Investigating the off-diagonal components of the conductivity and thermoelectric tensor of materials hosting complex antiferromagnetic structures has become a viable method to reve…
