Intra-unit-cell resolved intertwining of multi- charge and spin textures in an itinerant skyrmion magnet
Christopher J. Butler, Katsuki Nihongi, Haruto Yoshimochi +4
The mechanisms stabilizing non-collinear magnetism in centrosymmetric crystals remain unclear, but likely involve spin-spin interactions mediated by itinerant electrons, such as th…
Piezomagnetic transport in van der Waals noncoplanar Antiferromagnets
Abdul Ahad, Miuko Tanaka, Nguyen Duy Khanh +7
The piezomagnetic effect-strain-induced linear modulation of magnetization, arises in magnets with broken time-reversal symmetry (BTRS), offering a pathway to bidirectional strain-…
Large magneto-optical Kerr effect induced by collinear antiferromagnetic order
H. Yoshimochi, K. Yoshida, R. Oiwa +6
In modern technology, the optical readout of magnetic information is conventionally achieved by the magneto-optical Kerr effect, i.e., the polarization rotation of reflected light.…
Triangular lattice magnet GdGa with short-period spin cycloids and possible skyrmion phases
Priya R. Baral, Nguyen Duy Khanh, Masaki Gen +6
The two-dimensional triangular lattice (TAL) is a model system of magnetic frustration and competing interactions, where skyrmion spin vortices can be induced by a vertical magneti…
SP-STM study of the multi-Q phases in GdRu2Si2
Jonas Spethmann, Nguyen Duy Khanh, Haruto Yoshimochi +6
The two stable surfaces of GdRu2Si2 are studied using spin-polarized scanning tunneling microscopy (SP-STM). Depending on the applied magnetic field different magnetic phases have…
Gapped nodal planes drive a large topological Nernst effect in a chiral lattice antiferromagnet
N. D. Khanh, S. Minami, M. Hirschmann +15
The electronic structure of compensated antiferromagnets (CAF) has drawn attention for its ability to create large responses, reminiscent of ferromagnets and suitable for data stor…
