Competing magnetic correlations and uniaxial anisotropy in (Fe 1-x Mn x) 2 AlB 2 single crystals
Researchers synthesized single crystals of (Fe1-xMnx)2AlB2 across all Fe–Mn ranges using the Al self-flux method. They found that Mn substitution weakens ferromagnetic correlation in Fe2AlB2 while enhancing antiferromagnetic correlation in Mn2AlB2 up to x=0.65. The study reveals coexisting magnetic phases and competing uniaxial anisotropy between the a and b axes.
