{"status":"public","abstract":[{"text":"Magnetic anisotropy in strontium iridate (Sr2IrO4) is found to be large because of the strong spin-orbit interactions. In our work, we studied the in-plane magnetic anisotropy of Sr2IrO4 and traced the anisotropic exchange interactions between the isospins in the crystal. The magnetic-field-dependent torque τ(H) showed a prominent transition from the canted antiferromagnetic state to the weak ferromagnetic (WFM) state. A comprehensive analysis was conducted to examine the isotropic and anisotropic regimes and probe the easy magnetization axis along the a b plane. The angle-dependent torque τ(θ) revealed a deviation from the sinusoidal behavior, and small differences in hysteresis were observed around 0° and 90° in the low-magnetic-field regime. This indicates that the orientation of the easy axis of the FM component is along the b axis, where the antiferromagnetic to WFM spin-flop transition occurs. We compared the coefficients of the magnetic susceptibility tensors and captured the anisotropy of the material. The in-plane τ(θ) revealed a tendency toward isotropic behavior for fields with values above the field value of the WFM transition.","lang":"eng"}],"_id":"9065","day":"01","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","publication":"Physical Review B","publisher":"American Physical Society","author":[{"full_name":"Nauman, Muhammad","last_name":"Nauman","first_name":"Muhammad","orcid":"0000-0002-2111-4846","id":"32c21954-2022-11eb-9d5f-af9f93c24e71"},{"first_name":"Yunjeong","full_name":"Hong, Yunjeong","last_name":"Hong"},{"last_name":"Hussain","full_name":"Hussain, Tayyaba","first_name":"Tayyaba"},{"first_name":"M.
