Journal ArticleDOI
Chiral magnetic soliton lattice on a chiral helimagnet.
Yoshihiko Togawa,Tsukasa Koyama,Kazuya Takayanagi,Shigeo Mori,Yusuke Kousaka,Jun Akimitsu,Sadafumi Nishihara,Katsuya Inoue,A. S. Ovchinnikov,Jun-ichiro Kishine +9 more
TL;DR: Using Lorenz microscopy and small-angle electron diffraction, it is directly present that the chiral magnetic soliton lattice continuously evolves from a chiral helimagnetic structure in small magnetic fields in Cr(1/3)NbS2.
Journal ArticleDOI
Symmetry, Structure, and Dynamics of Monoaxial Chiral Magnets
TL;DR: The chiral soliton lattice appears under a magnetic field perpendicular to the chiral helical axis and is very robust and stable with phase coherence on a macroscopic length scale as discussed by the authors.
Journal ArticleDOI
Laser-Induced Skyrmion Writing and Erasing in an Ultrafast Cryo-Lorentz Transmission Electron Microscope.
Gabriele Berruto,I. Madan,Yoshie Murooka,Giovanni Maria Vanacore,Enrico Pomarico,Jayaraman Rajeswari,R. J. Lamb,Ping Huang,Alex Kruchkov,Yoshihiko Togawa,Yoshihiko Togawa,Yoshihiko Togawa,Thomas LaGrange,Damien McGrouther,Henrik M. Rønnow,Fabrizio Carbone +15 more
TL;DR: The Skyrmion lattice was found to maintain its structural properties during the laser-induced demagnetization, and its recovery to the initial state happened in the sub-μs to μs range, depending on the cooling rate of the system.
Journal ArticleDOI
Double-biprism electron interferometry
TL;DR: In this article, an electron holography based on two electron biprisms was developed, where the upper biprism was installed just on the image plane of the objective lens, and the lower one was set between the crossover point and image planes of the magnifying lens.
Journal ArticleDOI
Chiral Surface Twists and Skyrmion Stability in Nanolayers of Cubic Helimagnets.

TL;DR: Theoretical analysis and Lorentz transmission electron microscopy investigations in an FeGe wedge demonstrate that chiral twists arising near the surfaces of noncentrosymmetric ferromagnets provide a stabilization mechanism for magnetic Skyrmion lattices and helicoids in cubic helimagnet nanolayers.
