Abstract
Crystallization of La2/3Ba1/3MnO3+delta oxide, which resulted in a twin-typ e lamella microstructure, was studied in the present work. Thermomechanical and high-temperature x-ray diffraction analyses revealed that the twin cry stallization occurred at 548 K. The saturation magnetization of the twin-gr ained La2/3Ba1/3MnO3+delta oxide was shown much higher than the nontwin oxi des. This is probably due to the easy alignment of the domains by the rearr angement of the dislocations in the twin-grain boundaries. (C) 2001 America n Institute of Physics.
