dc.description.abstractWe report the magnetic structure and anisotropy of the quasi-one-dimensional S=12 antiferromagnet Na2CuSO4Cl2 obtained by single-crystal neutron scattering, electron spin resonance (ESR), and magnetization measurements, following an earlier study of its dynamics [M. Fujihala, Phys. Rev. B 101, 024410 (2020)10.1103/PhysRevB.101.024410]. A Néel-Type spin structure is formed within the chain of this compound, where the spins point along the b axis, and ESR data indicate an antisymmetric exchange with a uniform Dzyaloshinskii-Moriya (DM) vector pointing along the b axis. The anisotropy g factor and magnetic structure are strong indicators of magnetic anisotropy originating from a symmetric anisotropic exchange interaction and/or a magnetic dipole interaction. These results suggest that these terms of the anisotropic spin Hamiltonian counteract the effect of the DM interaction and stabilize the Néel-Type structure in Na2CuSO4Cl2. ©2022 American Physical Society.en_AU
dc.description.sponsorshipThe neutron scattering experiments were performed at the MLF (J-PARC) and OPAL reactor (ANSTO) under a user program (Proposals No. 2019A0106, No. P6517, and No. P6913). This study is supported by a Grant-in-Aid for Scientific Research (No. 21K03453 and No. 17K14344) from MEXT, Japan.en_AU
