The magnetic field due to a single vortex in anisotropic type-II superconductors with cubic crystal symmetry is calculated at T=0°K by means of the boson method. The results for the magnetic field are used in our analysis of stable orientation of the flux-line lattice with respect to the crystal lattice. The theoretical results agree well with the stable orientation of the flux-line lattice observed in weak-field region in Nb and Pb-Tl at low temperature. The boson characteristic function for cubic superconductors is also presented.
