First-principles study of magnetic and spin-dependent transport properties of Mn2VZ (Z = Al, Ga) with negative spin polarization using a disordered local moment approach at finite temperatures
Shogo Yamashita, Esita Pandey, Gerhard H. Fecher +2
First-principles studies were performed on two Mn-based ferrimagnetic Heusler compounds with L21 and B2 structures, that is, Mn2VZ (Z = Al or Ga). The aim was to investigate their…
Non-collinear magnetism contra frustration: Magnetic order and anisotropy in hexagonal MnPtGa
Gerhard H. Fecher, Roshnee Sahoo, Claudia Felser
MnPtGa is a hexagonal intermetallic compound with a rich variety of magnetic order. Its magnetic state is reported to range from collinear ferromagnetism, to non-collinear skyrmion…
Visualizing higher-fold topology in chiral crystals
Tyler A Cochran, Ilya Belopolski, Kaustuv Manna +21
Novel topological phases of matter are fruitful platforms for the discovery of unconventional electromagnetic phenomena. Higher-fold topology is one example, where the low-energy d…
Quantized nonlinear Hall effect from chiral monopole
Nikolai Peshcherenko, Claudia Felser, Yang Zhang
Nonlinear Hall effect arises in materials without inversion symmetry, and the intrinsic contribution is typically from Berry curvature dipole of non-universal Fermi pockets. Here w…
Pomeranchuk Instability Induced by an Emergent Higher-Order van Hove Singularity on the Distorted Kagome Surface of CoSnS
Pranab Kumar Nag, Rajib Batabyal, Julian Ingham +11
Materials hosting flat bands at the vicinity of the Fermi level promote exotic symmetry broken states. Common to many of these are van Hove singularities at saddle points of the di…
