Taking into account the spin-polarized effect,rough interface scattering and spin-flip effects,we calculate,within Blonder-Tinkham-Klapwijk Scattering formalism,the spin-polarized tunnel spectrum in the ferromagnet-d-wave superconductor junctions.It is shown that,(1) the conductance exhibits a sharp peak at zero-bias with the increase in spin-flip scattering;(2) the interface roughness can induce a small central peak in the zero-bias conductance dip and decrease the height of the zero-bias conductance peak.The calculated results can account for the tunnel spectrum observed experimentally in La2/3Ba1/3 MnO3/DyBa2Cu3O7 and La2/3 Ba1/3 MnO3/YBa2Cu3O7-δ junctions.
