Spontaneous topological Hall effect induced by non-coplanar antiferromagnetic order in intercalated van der Waals materials
H. Takagi, R. Takagi, S. Minami +14
In ferromagnets, electric current generally induces transverse Hall voltage in proportion to magnetization (anomalous Hall effect), and it is frequently used for electrical readout…
Rhombic skyrmion lattice coupled with orthorhombic structural distortion in EuAl
Masaki Gen, Rina Takagi, Yoshito Watanabe +9
The centrosymmetric tetragonal itinerant magnet EuAl exhibits an intricate magnetic phase diagram including rhombic and square skyrmion-lattice (SkL) phases in the external m…
Zoology of multiple-Q spin textures in a centrosymmetric tetragonal magnet with itinerant electrons
N. D. Khanh, T. Nakajima, S. Hayami +9
Magnetic skyrmion is a topologically stable particle-like swirling spin texture potentially suitable for high-density information bit, which was first observed in noncentrosymmetri…
Direct visualization of three-dimensional shape of skyrmion strings in a noncentrosymmetric magnet
S. Seki, M. Suzuki, M. Ishibashi +6
Magnetic skyrmion, i.e. a topologically stable swirling spin texture, appears as a particle-like object in the two-dimensional (2D) systems, and has recently attracted attention as…
Nanometric square skyrmion lattice in a centrosymmetric tetragonal magnet
N. D. Khanh, T. Nakajima, X. Z. Yu +12
Magnetic skyrmions are topologically stable spin swirls with particle-like character and potentially suitable for the design of high-density information bits. While most known skyr…
Increased lifetime of metastable skyrmions by doping
M. T. Birch, R. Takagi, S. Seki +12
Previous observations of metastable magnetic skyrmions have shown that close to the equilibrium pocket the metastable state has a short lifetime, and therefore rapid cooling is req…
