Foucault imaging and small-angle electron diffraction in controlled external magnetic fields
Hiroshi Nakajima, Atsuhiro Kotani, Ken Harada +2
We report a method for acquiring Foucault images and small-angle electron diffraction patterns in external magnetic fields using a conventional transmission electron microscope wit…
Electron diffraction covering a wide angular range from Bragg diffraction to small-angle diffraction
Hiroshi Nakajima, Atsuhiro Kotani, Ken Harada +1
We construct an electron optical system to investigate Bragg diffraction (the crystal lattice plane, - rad) with the objective lens turned off by adjusting the cu…
Charged domain walls and crystallographic microstructures in hybrid improper ferroelectric CaSrTiO
Hiroshi Nakajima, Koji Shigematsu, Yoichi Horibe +2
The charged domain walls in ferroelectric materials exhibit intriguing physical properties. We examine herein the charged-domain-wall structures in CaSrTiO usin…
Formation process of skyrmion lattice domain boundaries: The role of grain boundaries
Hiroshi Nakajima, Atsuhiro Kotani, Masahito Mochizuki +2
We report on the formation process of skyrmion lattice (SkL) domain boundaries in FeGe using Lorentz transmission electron microscopy and small-angle electron diffraction. We obser…
Glass-like features of crystalline solids in the quantum critical regime
Y. Ishii, Y. Ouchi, S. Kawaguchi +3
There has been growing interest in structural quantum phase transitions and quantum fluctuations of phonons in the research area of condensed matter physics. Here, we report the ob…
