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…
Manifestation of the Berry curvature in Co2TiSn Heusler films
Benedikt Ernst, Roshnee Sahoo, Yan Sun +7
Various Co2 based Heusler compounds are predicted to be Weyl materials. These systems with broken symmetry possess a large Berry curvature, and introduce exotic transport propertie…
Discovery of Magnetic Antiskyrmions Beyond Room Temperature in Tetragonal Heusler Materials
Ajaya K. Nayak, Vivek Kumar, Peter Werner +6
Skyrmions, topologically stable spin textures, are of great interest for new generations of spintronic devices. In general, the stabilization of skyrmions has been achieved in syst…
Field dependent neutron diffraction study in Ni50Mn38Sb12 Heusler alloy
Roshnee Sahoo, Amitabh Das, Norbert Stuesser +1
In this paper, we present temperature and field dependent neutron diffraction (ND) study to unravel the structural and the magnetic properties in Ni50Mn38Sb12 Heusler system. This…
Compensated ferrimagnetic tetragonal Heusler thin films for antiferromagnetic spintronics
Roshnee Sahoo, Lukas Wollmann, Susanne Selle +9
In recent years, antiferromagnetic spintronics has received much attention since ideal antiferromagnets do not produce stray fields and are much more stable to external magnetic fi…
Titanium Nitride as a Seed Layer for Heusler Compounds
Alessia Niesen, Manuel Glas, Jana Ludwig +5
Titanium nitride (TiN) shows low resistivity at room temperature, high thermal stability and thus has the potential to serve as seed layer in magnetic tunnel junctions. High qualit…
