Abstract

Polycrystalline perovskite-like manganites of the La1-cSrcMn1-xVxO3 system ($c=0.35$; 0.45; 0.55; $x=0.05$; 0.10) were synthesized using conventional ceramic processing. Sintering was carried out at 1473 K for 10 h. Then the samples were annealed under conditions that provide stoichiometric oxygen content.

Manganite with the lowest strontium and vanadium content is of rhombohedral structure, while the other samples are orthorhombic. All samples contain an impurity of SrV2O5 phase in the amount of from a few tenths to 2.5 mass %. The introduction of strontium and vanadium leads to decrease in the unit cell volume of perovskite phase.

Electromagnetic parameters of manganites change with the content of Sr and V as follows: specific magnetization at 80 K decreases from 71.8 to 49.2 emu/g; Curie point rises from 326 K to 340 K; width of the "ferromagnetic-paramagnetic" transition temperature interval increases; metallic type of conductivity in the 120--300 K range is replaced by a semiconducting nature for $c=0.55$; $x=0.10$. Manganite La0.55Sr0.45Mn0.95V0.05O3 has a maximum absolute value of magnetoresistance equal to 23 % in the field of 0.92 T at 120 K.

Possible approaches to the interpretation of the established regularities are discussed, taking into consideration the changes in the concentrations of different valence manganese ions and the ratio of competing exchange interactions, the formation of ferromagnetic clusters and possible violation of the percolation regime between them, the influence of second-phase segregations and localization of cation vacancies at the intercrystalline boundaries.
