- 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.
