Chiral magnetic excitations and domain textures of g-wave altermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Jorge I. Facio +5
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which opposite-spin sublattices are connected by a crystal rotation, causing their electronic iso-energ…
Controlling photo-excited electron-spin by light-polarization in ultrafast-pumped altermagnets
Amir Eskandari-asl, Jorge I. Facio, Oleg Janson +2
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which the symmetry connecting opposite-spin sublattices involves a spatial rotation. Here, we uncover a…
Site-selective observation of spin dynamics of a Tomonaga-Luttinger liquid in frustrated Heisenberg chains
Diep Minh Nguyen, Azimjon A. Temurjonov, Daigorou Hirai +6
Low-energy spin dynamics is investigated by Cl NMR measurements in a frustrated antiferromagnet CaReOCl. The local spin susceptibility measured with the Knight…
Influence of pressure on properties of multi-gap type-I superconductor BeAu
Rustem Khasanov, Riccardo Vocaturo, Oleg Janson +7
We report on studies of the superconducting and normal state properties of the noncentrosymmetric superconductor BeAu under hydrostatic pressure conditions. The room-temperature eq…
Spin Hall and Edelstein Effects in Novel Chiral Noncollinear Altermagnets
Mengli Hu, Oleg Janson, Claudia Felser +3
Altermagnets are a newly discovered class of magnetic phases that combine the spin polarization behavior of ferromagnetic band structures with the vanishing net magnetization chara…
