The magnetization of the single crystal of a molecular magnet [(C_6H_15N_3)_6Fe_8O_2(OH)_12] Br_7(H_2O)Br・8H_2O, Fe8, has been measured in the temperature down to 1.8 K and the field up to 5 T. The molecule Fe8 consists of eight Fe^<3+> ions with spins s = 5/2. The magnetization at low temperatures shows large anisotropy depending on the orientation of the external magnetic field. The temperature and magnetic field dependences of the magnetization are well explained by the Hamiltonian for the isolated molecules with total spins S = 10. The anisotropies of D and E are estimated to be -0.276 K and -0.035 K, respectively.
