Magnetization measurements were made on a single crystal of ferromagnetic MnAlGe from 4.2 K to 350 K in order to determine the uniaxial magnetic anisotropy constant K_1. The saturation moment and K_1 extrapolated to 0 K are 1.70 μ_B/Mn and 9.7×10^6erg/cc, respectively. The observed temperature dependence of K_1, after corrected for dipole-dipole interaction energy, is expressed in terms of the saturation magnetization σ as 10.7×10^6[σ(T)/σ(O)]^<3.08> erg/cc, in good agreement with the spin wave theory which predicts the exponent 3.
