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…
Glasslike phonon excitation caused by ferroelectric structural instability
Y. Ishii, A. Yamamoto, N. Sato +5
Quest for new states of matter near an ordered phase is a promising route for making modern physics forward. By probing thermal properties of a ferroelectric (FE) crystal Ba1-xSrxA…
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…
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…
Observation of magnetic domain and bubble structures in magnetoelectric SrCoFeO
H. Nakajima, H. Kawase, K. Kurushima +3
The magnetic domain and bubble structures in the Z-type hexaferrite SrCoFeO were investigated using Lorentz microscopy. This hexaferrite exhibits a room-tempe…
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…
