Spin-flip-driven reversal of the angle-dependent magnetic torque in layered antiferromagnetic Ca_0.9Sr_0.1Co₂As₂.

ABSTRACT: Spin-flip transition can occur in antiferromagnets with strong magnetocrystalline anisotropy, inducing a significant modification of the anisotropic magnetic properties through phase conversion. In contrast to ferromagnets, antiferromagnets have not been thoroughly examined in terms of their anisotropic characteristics. We investigated the magnetic-field and angle-dependent magnetic properties of Ising-type antiferromagnetic Ca_0.9Sr_0.1Co₂As₂ using magnetic torque measurements. An A-type antiferromagnetic order emerges below T_N = 97 K aligned along the magnetically easy c-axis. The reversal of the angle-dependent torque across the spin-flip transition was observed, revealing the strong influence of the magnetocrystalline anisotropy on t
