All rights reserved.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.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Ferromagnetic and anti-ferromagnetic,Magnetic interactions,Magnetic response,Octahedral layers,Perovskite compounds,Spin state,Structural correlation,Structural modifications[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Co-based perovskite compounds: Sr0.775Y0.225(Co0.9TM0.1)O3- (TM = Fe,Zn),Co3+ spin states,Doping induced effects,Ferromagnetic and antiferromagnetic orderings,Magnetic and local structural correlation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The results in this research are funded by Science and Technology Research Grant from Indonesia Toray Science Foundation (ITSF) 2013 and Riset dan Inovasi KK ITB 2013 research program under contract number: 229/I.1.C01/PL/2013.
