Magnetoelastic effects in the metallic frustrated antiferromagnet CrB
Tadataka Watanabe, Mai Watanabe, Sakurako Suganuma +2
Hexagonal chromium diboride CrB is a metallic frustrated antiferromagnet with a Néel temperature 88 K. In CrB, Cr 3 electrons not only give rise to localized…
Non-reciprocal spin excitations across the skyrmion-paramagnetic phase transition in MnSi
Tobias Weber, Karin Schmalzl, Johannes Waizner +3
The magnetic excitations of the skyrmion lattice in MnSi comprise a multitude of individual modes, which are non-reciprocal and thereby propagate unidirectionally. We report inelas…
Spin-density wave of ferrimagnetic building blocks masking the ferromagnetic quantum-critical point in NbFe2
T. Poulis, G. Mani, J. Sturt +11
In the metallic magnet NbFe2, the low temperature threshold of ferromagnetism can be investigated by varying the Fe concentration within a narrow homogeneity range. NbFe2 is one of…
Non-Reciprocal Zone Boundary Magnon Propagation in CuOSeO
Tobias Weber, Niclas Heinsdorf, Michal Stekiel +3
Inelastic neutron scattering in the chiral magnet CuOSeO reveals strong non-reciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The non-…
Easy-plane ferromagnetism in single-crystal ErB at low temperatures
Christoph Resch, Georg Benka, Andreas Bauer +1
We report a study of single crystals of the hexagonal rare-earth diboride ErB prepared by means of the self-adjusted flux travelling-solvent floating-zone technique. Measurem…
Fermi surface and magnetic breakdown in PdGa
Nico Huber, Ivan Volkau, Alexander Engelhardt +4
We study the electronic structure of the chiral semimetal PdGa by means of the de Haas-van Alphen and Shubnikov-de Haas effect. We find that the Fermi surface of PdGa comprises mul…
