dcterms:description
Substituce na poloze Co u vzorků LaCoO3 zachová magnetický přechod u 100 K a resistivní přechod okolo 500 K, charakteristické pro nedopovaný LaCoO3. Ale nízkoteplotní transportní a magnetické vlastnosti jsou velmi odlišné pro dopované a nedopované vzorky. Přidané náboje vytváří teplotně stabilní magnetické polarony. The samples LaCoO3 with dilute substitutions on cobalt sites have been studied using the resistivity, thermopower and magnetic susceptibility measurements over the temperature range up to 900 K. The Co-site substitution does not affect the magnetic transition at 100 K and the onset of massive population of hole carriers at 500 K, characteristic for undoped LaCoO3. On the other hand, the lowtemperature transport and magnetism is markedly distinct for samples with extra charge on cobalt ions introduced by the heterovalent dopants (Mg2+, Ti4+) compared to samples with minor non-stoichiometry (LaCoO3, Ga3+-doped sample). Magnetic properties suggest that these extra charges create thermally stable magnetic polarons of total S similar to 2–3. Common features of Co-site doped and La-site doped samples (La1-xSrxCoO3) are discussed.
