The influence of magnetocrystalline anisotropy in antiferromagnets is evident in a spin flip or flop transition. Contrary to spin flops, a spin-flip transition has been scarcely presented due to its specific condition of relatively strong magnetocrystalline anisotropy and the role of spin-flips on anisotropic phenomena has not been investigated in detail. In this study, we present antiferromagnet-based functional properties on an itinerant Ising antiferromagnet CaSrCoAs. In the presence of a rotating magnetic field, anomalous Hall conductivity and anisotropic magnetoresistance are demonstrated, the effects of which are maximized above the spin-flip transition. Moreover, a joint experimental and theoretical study is conducted to provide an efficient tool to identify various spin states, which can be useful in spin-processing functionalities.
反铁磁体中的磁晶各向异性的影响在自旋翻转或反转跃迁中显而易见。与自旋反转不同，由于其较强的磁晶各向异性的特定条件以及自旋翻转对各向异性现象的作用尚未得到详细研究，自旋翻转跃迁很少出现。在这项研究中，我们在巡游伊辛反铁磁体 CaSrCoAs 上展示了基于反铁磁体的功能特性。在旋转磁场的存在下，演示了反常霍尔电导率和各向异性磁阻，其效果在自旋翻转跃迁之上达到最大值。此外，进行了联合实验和理论研究，为识别各种自旋态提供了一种有效的工具，这在自旋处理功能中可能很有用。
