Two types of magnetic bubbles in MnNiGa observed via Lorentz microscopy
Hiroshi Nakajima, Atsuhiro Kotani, Ken Harada +1
Magnetic bubbles are remarkable spin structures that developed in uniaxial magnets with strong magnetocrystalline anisotropy. Several contradictory reports have been published conc…
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…
Van der Waals Heterostructure Magnetic Josephson Junction
H. Idzuchi, F. Pientka, K. -F. Huang +9
When two superconductors are connected across a ferromagnet, the spin configuration of the transferred Cooper pairs can be modulated due to magnetic exchange interaction. The resul…
Magnetic bubbles in an M-type hexagonal ferrite observed by hollow-cone Foucault imaging and small-angle electron diffraction
Atsuhiro Kotani, Hiroshi Nakajima, Atsushi Kawaguchi +5
We report hollow-cone imaging and small-angle electron diffraction of nanoscale magnetic textures such as magnetic-striped domains and magnetic bubbles of M-type hexagonal ferrite…
Lorentz microscopy and small-angle electron diffraction study of magnetic textures in LaSrMnO (0.15 0.30): the role of magnetic anisotropy
A. Kotani, H. Nakajima, K. Harada +2
Magnetic textures in the ferromagnetic phases of LaSrMnO for 0.15 0.30 have been investigated by Lorentz microscopy combined with small-angle electron diffr…
Field-temperature phase diagram of magnetic bubbles spanning chargeorbital ordered and metallic phases in LaSrMnO ()
A. Kotani, H. Nakajima, K. Harada +2
We report formation of magnetic textures in the ferromagnetic (FM) phase of LaSrMnO for 0.125; these textures are magnetic bubbles, magnetic stripe domains, a…
