Unusual nanoscale coexistence of polar-nonpolar domains underlying oxygen storage properties in Ho(Mn, Ti)O
Hiroshi Nakajima, Kento Uchihashi, Hirofumi Tsukasaki +10
Hexagonal manganese oxides RMnO show intriguing topological ferroelectric-domain walls with variable conductivity, leading to domain wall engineering. Despite the numerous expe…
Stabilization of layered perovskite structures via strontium substitution in CaTiO revealed via elemental mapping
Kosuke Kurushima, Hiroshi Nakajima, Shinya Mine +5
Extensive studies have been performed on layered compounds, ranging from layered cuprates to van der Waals materials with critical issues of intergrowths and stacking faults. Howev…
Charged domain boundaries stabilized by translational symmetry breaking in the hybrid improper ferroelectric CaSrTiO
Hiroshi Nakajima, Kosuke Kurushima, Shinya Mine +5
Charged domain walls and boundaries in ferroelectric materials display distinct phenomena, such as an increased conductivity due to the accumulation of bound charges. Here, we repo…
Magnetic textures in a hexaferrite thin film and their response to magnetic fields revealed by phase microscopy
Atsuhiro Kotani, Ken Harada, Marek Malac +3
We investigated magnetic textures in a Sc-doped hexaferrite film by means of phase microscopy (PM) with a hole-free phase plate in a transmission electron microscope. In a zero mag…
Is hexagonal InMnO3 ferroelectric?
F. -T. Huang, X. Wang, Y. S. Oh +4
The presence of ferroelectricity in hexagonal (h-)InMnO3 has been highly under debate. The results of our comprehensive experiments of low-temperature (T) polarization, TEM and HAA…
