Near room temperature antiferromagnetic ordering with a potential low dimensional magnetism in AlMn${}_2$B${}_2$

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${}_2$.
