Observation of magnetic inhomogeneities in crystalline-doped manganites by electron magnetic resonance Academic Article uri icon

abstract

  • Abstract Electron magnetic resonance measurements were employed for studying the magnetic spin structure in bulk and crushed crystalline samples of doped La 0.888 Na 0.113 Mn 0.997 O 3 and La 0.833 Sn 0.126 Mn 0.997 O 3, and self-doped La 0.94 Mn 0.98 O 3, grown by fused-salt electrolysis. The ferromagnetic resonance exhibits a common characteristic multiline spectrum for single crystals and “noiselike” oscillations superimposed on ferromagnetic signal for crushed crystals. A coexistence of ferromagnetic and electron …
