--- res: bibo_abstract: - Magnetic anisotropy in strontium iridate (Sr2IrO4) is essential because of its strong spin–orbit coupling and crystal field effect. In this paper, we present a detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for different sample orientations using torque magnetometry measurements in the low-magnetic-field region before the isospins are completely ordered. Dominant in-plane anisotropy was identified at low fields, confirming the b axis as an easy magnetization axis. Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange interaction affecting the OOP interaction. The effect of interlayer exchange interaction results in additional anisotropic terms owing to the tilting of the isospins. The results are relevant for understanding OOP magnetic anisotropy and provide a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic exchange interactions. This study provides insight into the understanding of bulk magnetic, magnetotransport, and spintronic behavior on Sr2IrO4 for future studies.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Muhammad foaf_name: Nauman, Muhammad foaf_surname: Nauman foaf_workInfoHomepage: http://www.librecat.org/personId=32c21954-2022-11eb-9d5f-af9f93c24e71 orcid: 0000-0002-2111-4846 - foaf_Person: foaf_givenName: Tayyaba foaf_name: Hussain, Tayyaba foaf_surname: Hussain - foaf_Person: foaf_givenName: Joonyoung foaf_name: Choi, Joonyoung foaf_surname: Choi - foaf_Person: foaf_givenName: Nara foaf_name: Lee, Nara foaf_surname: Lee - foaf_Person: foaf_givenName: Young Jai foaf_name: Choi, Young Jai foaf_surname: Choi - foaf_Person: foaf_givenName: Woun foaf_name: Kang, Woun foaf_surname: Kang - foaf_Person: foaf_givenName: Younjung foaf_name: Jo, Younjung foaf_surname: Jo bibo_doi: 10.1088/1361-648X/ac484d bibo_issue: '13' bibo_volume: 34 dct_date: 2022^xs_gYear dct_identifier: - UT:000775191800001 dct_isPartOf: - http://id.crossref.org/issn/1361-648X dct_language: eng dct_publisher: IOP Publishing@ dct_title: Low-field magnetic anisotropy of Sr2IrO4@ fabio_hasPubmedId: '34986467' ...
