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…

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…
