Abstract

Structural and magnetic properties of Cr-based compound CrAlGe were investigated. The crystal structure was found to be an orthorhombic TiSi₂-type with lattice parameters a = 0.4770 nm, b = 0.8254 nm and c = 0.8725 nm at room temperature. Magnetization curve of CrAlGe showed the ferromagnetic behavior. The saturation magnetic moment, spontaneous magnetic moment and Curie temperature of CrAlGe were determined to be 0.45 μ_B/f.u., 0.41 μ_B/f.u. and T_C = 80 K, respectively. For the temperature T below 30 K, the decrease in the square of the spontaneous magnetization M₀(T)² was proportional to T². However, for 30 < T < T_C, the decrease in M₀(T)² was proportional to T^4/3. Obtained results suggest that CrAlGe is a weak itinerant electron ferromagnet.
