摘要：

A study is conducted on the relation between dopant induced changes in magnetic properties and local structural modifications in Sr0.775Y0.225(Co0.9Zn0.1)O3-. Temperature and field dependent magnetic responses of this compound are found to differ from those previously reported for Sr0.775Y0.225(Co0.9Fe0.1)O3-. The Fe-doped compound show near total suppression of FM, while Zn-doped compound retain measurable FM ordering. Local structures are shown to exhibit perceptible differences of Co-O bond lengths and Co-O-Co bond angles in the fully oxygenated octahedral layer. Those differences are argued to result in the different CF strengths that affect differently the Co3+ spin states and the inter-ionic magnetic interactions. © 2018 Politechnica University of Bucharest.
