Polycrystalline samples of the new superconducting compound EuAsFeO0.85F0.15, with critical temperature Tc=11K, are prepared by solid state synthesis. Its electric and magnetic properties are investigated in magnetic fields from 0.1to140000Oe. The critical magnetic fields Hc1 and Hc2 are measured, and thence the magnetic penetration depth λ and the coherence length ξ are estimated. The temperature dependence Hc2(T) exhibits clear hyperbolic-type behavior starting with the lowest fields. The data derived were used to estimate probable high Tc and Hc2 in compounds doped with rare earths having small atomic radii.
