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\u2009=\u20090) to antiferromagnetic (compounds with x \u2265 0.1) while the temperature of a transition into paramagnetic state remains about 270\u2009K 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+\u2013O\u2013Mn4+ while the interaction between Ni3+ and Mn4 ions is considered to be strongly antiferromagnetic.<\/jats:p>","DOI":"10.1063\/1.5001300","type":"journal-article","created":{"date-parts":[[2017,10,5]],"date-time":"2017-10-05T18:22:00Z","timestamp":1507227720000},"page":"982-985","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Antiferromagnet-ferromagnet transition in La1\u2013xSrxMn0.5Ni0.5O3 (0\u2009\u2264\u2009x\u2009\u2264\u20090.2) ceramics"],"prefix":"10.1063","volume":"43","author":[{"given":"I.
