Query: Charge current in ferromagnet-superconductor junction with pairing state
  of broken time-reversal symmetry   We calculate the tunneling conductance spectra of a ferromagnetic
metal/insulator/superconductor using the Blonder-Tinkham-Klapwijk (BTK)
formulation. Two possible states for the superconductor are considered with the
time reversal symmetry ($\cal{T}$) broken, i.e., $d_{x^2-y^2}+is$, or
$d_{x^2-y^2}+id_{xy}$. In both cases the tunneling conductance within the gap
is suppressed with the increase of the exchange interaction due to the
suppression of the Andreev reflection. In the $(d_{x^2-y^2}+is)$-wave case the
peaks that exist when the ferromagnet is a normal metal in the amplitude of the
s-wave component due to the bound state formation are reduced symmetrically,
with the increase of the exchange field, while in the
$(d_{x^2-y^2}+id_{xy})$-wave case the residual density of states within the gap
develops a dip around E=0 with the increase of the exchange field. These
results would be useful to discriminate between $\cal{T}$-broken pairing states
near the surface in high-$T_c$ superconductors
