Abstract

We present self flux growth and characterization of single crystalline AlMn $_2$ B $_2$ . It is an orthorhombic (space group Cmmm), layered material with a plate like morphology. The anisotropic bulk magnetization data, electrical transport and $^{11}$ B nuclear magnetic resonance(NMR) data revealed an antiferromagnetic (AFM) transition at 313 $\pm$ 2 K. In the magnetization data, there is also a broad local maximum significantly above the AFM transition that could be a signature of low dimensional magnetic interactions in AlMn $_2$ B $_2$ .
