Electron magnetic resonance (EMR) in sonochemically prepared doped nano-manganites Academic Article uri icon

abstract

  • X-band electron magnetic resonance method was explored for study of sonochemically prepared nano-powders of La-based doped manganites: La0. 7Sr0. 3MnO3 and La0. 9Ca0. 1MnO3 at 115⩽ T⩽ 600K temperature interval, including main characteristic points of its magnetic transitions. The data obtained were compared with those for crushed bulk single crystals of the same compositions. It is shown that nano-powder of La0. 7Sr0. 3MnO3 has the same ferromagnetic ordering as its bulk counterpart, being more homogeneous and …
