We report the measurements of the anisotropic magnetization and magnetoresistance (MR) on single crystals of EuFe 2 As 2, a parent compound of ferro-arsenide high-temperature superconductor. Apart from the antiferromagnetic (AFM) spin density wave (SDW) transition at 186 K associated with Fe moments, the compound undergoes another magnetic phase transition at 19 K due to AFM ordering of Eu 2+ spins (J= S= 7/2). The latter AFM state exhibits metamagnetic (MM) transition under magnetic fields. Upon applying magnetic field with H∥ c at 2 K, the magnetization increases linearly to 7.0 μ B fu− 1 at μ 0 H= 1.7 T and then remains at this value for saturated Eu 2+ moments under higher fields. In the case of H∥ ab, the magnetization increases step-like to 6.6 μ B fu− 1 with small magnetic hysteresis. An MM phase was identified with the saturated moments of 4.4 μ B fu− 1. The MM transition accompanies …
