Temperature dependence of the anisotropic magnetic field penetration depth of a two-band superconductor is calculated in the model of strong *-wave pairing interaction in one of the bands (5-band) and induced superconductivity in the second band (iV-band). The results of the calculations are compared with experimental data on the ab-plane and c-axis penetration depth in õ÷ÁÇóÉÚ07_^. It is shown that all recent measurements in the entire temperature range are consistent with the two-band model.
