[Editors' Suggestion] The authors report here on the synthesis and properties of the intergrowth compound Eu₂CuZn₂As₃, designed by structurally hybridizing two known magnetic topological materials, EuCuAs and EuZn₂As₂. It exhibits a complex antiferromagnetic ground state with multiple transitions, a significant negative magnetoresistance, and a nonlinear anomalous Hall effect. The work demonstrates structural hybridization as an effective strategy for discovering new magnetic topological materials with tailored properties.

我们课题组在美国物理学会(APS)期刊Physical Review B发表题为“Design, synthesis, and physical properties of the intergrowth compound Eu₂CuZn₂As₃”的论文，并入选编辑推荐。这是我们课题组继Eu₂CuMn₂P₃的研究后，又一篇关于‘2123’型交生结构化合物的报道。Eu2CuZn2As3除了具有多重磁转变外，它还展现出了与组成块层EuCuAs和EuZn₂As₂类似的非线性反常霍尔效应。此外，理论计算表明Eu2CuZn2As3可能具有丰富的拓扑非平庸态。我们的研究表明利用块层堆叠的方式可以有效地设计出具有拓扑非平庸性质的新型磁性材料。
