Title: Magnetic properties of single crystalline itinerant ferromagnet AlFe 2 B 2

Here, single crystals of AlFe 2B 2 have been grown using the self-flux growth method, and then we measured the structural properties, temperature- and field-dependent magnetization, and temperature-dependent electrical resistivity at ambient as well as high pressure. The Curie temperature of AlFe 2B 2 is determined to be 274 K. The measured saturation magnetization and the effective moment for the paramagnetic Fe ion indicate the itinerant nature of the magnetism with a Rhode-Wohlfarth ratio M C/M sat ≈ 1.14. Temperature-dependent resistivity measurements under hydrostatic pressure show that transition temperature TC is suppressed down to 255 K for p = 2.24 GPa pressure with a suppression rate of ~–8.9 K/GPa. The anisotropy fields and magnetocrystalline anisotropy constants are in reasonable agreement with density functional theory calculations.
