Figure 1

(a) Crystal structure of EuMnBi2 and its magnetic structure in the temperature (T) range of TN(Eu) ≤ T ≤ TN(Mn) (top row) and T ≤ TN(Eu) (bottom row). Mn magnetic moments are indicated by purple arrows, while Eu moments by green arrows. (b) Temperature dependence of the magnetization (M). The magnetization was measured in magnetic field of 0.1 T applied along the c axis. The open triangle indicates the antiferromagnetic transition temperature of Eu ions, TN(Eu). (c) Temperature dependence of inplane and interlayer resistivities, ρxx and ρzz, respectively. The inset shows the magnified view of the temperature dependence of ρzz in the high temperature regime. The open triangles indicate the antiferromagnetic transition temperature of Eu ions (TN(Eu)) and the closed triangle the antiferromagnetic transition temperature of Mn ions (TN(Mn)).
