Abstract
The single crystals of the topological material candidate EuZnBi\(_{2}\) have been grown using flux method, and the magnetic properties have been systematically investigated. Crystal structure analysis confirms that EuZnBi\(_{2}\) crystallizes in a layered tetragonal structure at room temperature, consisting of alternating ZnBi\(_{4}\) tetrahedral and Bi planar layers, separated by Eu atoms. The direct current (DC) magnetic susceptibility, alternating current (AC) magnetic susceptibility, and specific heat measurements indicate that a long-range antiferromagnetic order of Eu\(^{2+}\) develops at T\(_{N}\) = 20 K and the magnetic easy axis exists in the layers. It is interesting to note that EuZnBi\(_{2}\) exhibits a magnetic anomaly below T\(_{N}\), which might be associated with the tilting of Eu moments and spin reorientation.
