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…
Formation mechanisms of magnetic bubbles in an M-type hexaferrite: the role of chirality reversals at domain walls
H. Nakajima, A. Kotani, K. Harada +2
We examined the formation mechanisms of magnetic bubbles in an M-type hexaferrite via Lorentz microscopy. When magnetic fields were perpendicularly applied to a thin sample of BaFe…
Observation of magnetic domains in uniaxial magnets via small-angle electron diffraction and Foucault imaging
Hiroshi Nakajima, Atsuhiro Kotani, Ken Harada +1
Observation of magnetic domains is important in understanding the magnetic properties of magnetic materials and devices. In this study, we report that the magnetic domains of M-typ…
