Behavior of magnetic domains inLa0.46Sr0.54MnO3during the ferromagnetic phase transformation studied by electron holography

Behavior of magnetic domains during the ferromagnetic-to-paramagnetic transformation in La 0 . 4 6 Sr 0 . 5 4 MnO 3 was examined by in situ observations of electron holography. Microscopic observations of the magnetic flux inside the specimen revealed an inhomogeneous manner of elimination of the ferromagnetism. Two principal modes of elimination of closure magnetic domains were discovered, i.e., simple shrinkage and splitting into a few small parts.
