Near room temperature antiferromagnetic ordering with a potential low-dimensional magnetism in A1Mn2 B2
We present self flux growth and characterization of single crystalline AlMn2B2. It is an orthorhombic (space group Cmmm), layered material with a platelike morphology. The anisotropic bulk magnetization data, electrical transport, and 11B nuclear magnetic resonance (NMR) data revealed an antiferromagnetic (AFM) transition at 313 ± 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 AlMn2B2.
