Antiferromagnet-ferromagnet transition in La₁–xSrxMn₀.₅Ni₀.₅O₃ (0 ≤ x ≤ 0.2) ceramics
Ceramics samples of La₁–xSrxMn₀.₅Ni₀.₅O₃ (0 ≤ x ≤ 0.2) with perovskite structure have been studied by neutron diffraction method, magnetometry and magnetoresistance measurements. Structural data testify a partial order of the Ni and Mn ions in all the compounds in spite of chemical substitution of t...

| description | Ceramics samples of La₁–xSrxMn₀.₅Ni₀.₅O₃ (0 ≤ x ≤ 0.2) with perovskite structure have been studied by neutron diffraction method, magnetometry and magnetoresistance measurements. Structural data testify a partial order of the Ni and Mn ions in all the compounds in spite of chemical substitution of the La³⁺ ions by Sr²⁺ ones and an increase of the oxidation state of the Ni ions from 2+ towards to 3+ one. Magnetic structure of the compounds changes from ferromagnetic one (specific for the compound with x = 0) to antiferromagnetic (compounds with x ≥ 0.1) while the temperature of a transition into paramagnetic state remains about 270 K for all the samples. Magnetoresistance gradually decreases with temperature increase and strontium content. The results are discussed assuming nearly equal ferromagnetic and antiferromagnetic components of the superexchange interaction Ni²⁺–O–Mn⁴⁺ while the interaction between Ni³⁺ and Mn⁴ ions is considered to be strongly antiferromagnetic.
