Topological melting of the metastable skyrmion lattice in the chiral magnet CoZnMn
Victor Ukleev, Daisuke Morikawa, Kosuke Karube +6
In a -Mn-type chiral magnet CoZnMn, we demonstrate that the magnetic field-driven collapse of a room temperature metastable topological skyrmion lattice passes throu…
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…
Metastable solitonic states in the strained itinerant helimagnet FeGe
Victor Ukleev, Yuichi Yamasaki, Oleg Utesov +5
The tensile strain is a promising tool for creation and manipulation of magnetic solitonic textures in the chiral helimagnets via tunable control of magnetic anisotropy and Dzyalos…
Element-specific soft X-ray spectroscopy, scattering and imaging studies of skyrmion-hosting compound CoZnMn
V. Ukleev, Y. Yamasaki, D. Morikawa +10
A room-temperature skyrmion-hosting compound CoZnMn has been examined by means of soft X-ray absorption spectroscopy, resonant small-angle scattering and extended refer…
Controlling the helicity of magnetic skyrmions in a -Mn-type high-temperature chiral magnet
K. Karube, K. Shibata, J. S. White +8
Magnetic helices and skyrmions in noncentrosymmetric magnets are representative examples of chiral spin textures in solids. Their spin swirling direction, often termed as the magne…
Spin-wave spectroscopy on Dzyaloshinskii-Moriya interaction in room-temperature chiral magnets hosting skyrmions
R. Takagi, D. Morikawa, K. Karube +8
Propagation character of spin wave was investigated for chiral magnets FeGe and Co-Zn-Mn alloys, which can host magnetic skyrmions near room temperature. On the basis of the freque…
Electrical magnetochiral effect induced by chiral spin fluctuations
T. Yokouchi, N. Kanazawa, A. Kikkawa +6
Chirality of matter can produce unique responses in optics, electricity and magnetism. In particular, magnetic crystals transmit their handedness to the magnetism via antisymmetric…
Temperature and magnetic field dependence of the internal and lattice structures of skyrmions by off-axis electron holography
K. Shibata, A. Kovács, N. Kanazawa +2
The internal and lattice structures of magnetic skyrmions in B20-type FeGe are investigated using off-axis electron holography. The temperature, magnetic field and angular dependen…
Nonreciprocal spin wave propagation in chiral-lattice ferromagnets
S. Seki, Y. Okamura, K. Kondou +8
Spin current, i.e. the flow of spin angular momentum or magnetic moment, has recently attracted much attention as the promising alternative for charge current with better energy ef…
Real-space observation of short-period cubic lattice of skyrmions in MnGe
Toshiaki Tanigaki, Kiyou Shibata, Naoya Kanazawa +6
Emergent phenomena and functions arising from topological electron-spin textures in real space or momentum space are attracting growing interest for new concept of states of matter…
Skyrmions with varying size and helicity in composition-spread helimagnetic alloys
K. Shibata, X. Z. Yu, T. Hara +6
The chirality, i.e. left or right handedness, is an important notion in a broad range of science. In condensed matter, this occurs not only in molecular or crystal forms but also i…
