Journal ArticleDOI
Transformation between meron and skyrmion topological spin textures in a chiral magnet
Xiuzhen Yu,Wataru Koshibae,Yusuke Tokunaga,Kiyou Shibata,Yasujiro Taguchi,Naoto Nagaosa,Naoto Nagaosa,Y. Tokura,Y. Tokura +8 more
TL;DR: Real-space observations of spin textures in a thin plate of the chiral-lattice magnet Co8Zn9Mn3, which exhibits in-plane magnetic anisotropy, demonstrate the rich variety of topological spin textures and their lattice forms and should stimulate further investigation of emergent electromagnetic properties.
Journal ArticleDOI
Towards control of the size and helicity of skyrmions in helimagnetic alloys by spin-orbit coupling
Kiyou Shibata,Xiuzhen Yu,Toru Hara,Daisuke Morikawa,Naoya Kanazawa,Koji Kimoto,Shintaro Ishiwata,Yoshio Matsui,Yoshinori Tokura,Yoshinori Tokura +9 more
TL;DR: The correlation between skyrmion helicity and crystal chirality in alloys of helimagnets Mn(1-x)Fe(x)Ge with varying compositions is reported on by Lorentz transmission electron microscopy and convergent-beam electron diffraction over a broad range of compositions.
Journal ArticleDOI
Large anisotropic deformation of skyrmions in strained crystal.
Kiyou Shibata,Junichi Iwasaki,Naoya Kanazawa,Shinji Aizawa,Toshiaki Tanigaki,Manabu Shirai,Taro Nakajima,Masashi Kubota,Masashi Kawasaki,Hyun Soon Park,Daisuke Shindo,Naoto Nagaosa,Yoshinori Tokura +12 more
TL;DR: The results show that the change in the modulation of the strength of this interaction is amplified by two orders of magnitude with respect to changes in the crystal lattice due to an applied strain, which may provide a mechanism to achieve strain control of topological magnetic structures based on the Dzyaloshinskii-Moriya interaction.
Journal ArticleDOI
Real-Space Observation of Short-Period Cubic Lattice of Skyrmions in MnGe.
Toshiaki Tanigaki,Toshiaki Tanigaki,Kiyou Shibata,Naoya Kanazawa,Xiuzhen Yu,Yoshinori Onose,Hyun Soon Park,Daisuke Shindo,Daisuke Shindo,Yoshinori Tokura,Yoshinori Tokura +10 more
TL;DR: This work reports real-space observations of spin configurations of the skyrmion-antiskyrmions cubic-lattice in MnGe with a very short period and hence endowed with the largest skyrMion number density.
Journal ArticleDOI
Nanometric square skyrmion lattice in a centrosymmetric tetragonal magnet
N. D. Khanh,N. D. Khanh,Taro Nakajima,Taro Nakajima,Xiuzhen Yu,Shang Gao,Shang Gao,Kiyou Shibata,Kiyou Shibata,Max Hirschberger,Max Hirschberger,Yuichi Yamasaki,Yuichi Yamasaki,Yuichi Yamasaki,Hajime Sagayama,Hironori Nakao,Licong Peng,Kenji Nakajima,Rina Takagi,Rina Takagi,Taka-hisa Arima,Taka-hisa Arima,Yoshinori Tokura,Yoshinori Tokura,Shinichiro Seki +24 more
TL;DR: The results suggest that rare-earth intermetallics with highly symmetric crystal lattices may ubiquitously host nanometric skyrmions of exotic origins, which are potentially suitable for the design of high-density information bits.
