The model makes use of the assumption that the axes of symmetry of all nanoparticles are aligned and oriented at a certain angle $\\psi$ with respect to the external magnetic field. An analytical expression for the temperature dependence of the susceptibility $\\chi(T)$ above the blocking temperature is obtained. The derived expression is a generalization of the Curie law for the case of anisotropic magnetic particles.
