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...

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.
