Abstract

Ferromagnetic resonance and ac/dc magnetic properties of the low-doped La _0.88Ca _0.12MnO ₃ and La _0.9Sr _0.1MnO ₃ manganite single crystals were studied below (down to 5 K) their paramagnetic-ferromagnetic phase transition. It appears that technologically driven chemical/structural disorder inherent to low-doped manganites influences strongly on both resonance and magnetic properties of these crystals. It is suggested that a special complexity of such disorder, which manifests itself in Sr-doped crystal on the meso- and macroscopic scales, may cause additional (as compared to the more structurally homogeneous Ca-doped sample) orbital ordering at lowest temperatures.
