Abstract
Tunneling conductance in ferromagnet/unconventional superconductor junctions is studied theoretically as a function of temperature and spin polarization in ferromagnets. In d-wave superconductor junctions, a zero-energy Andreev bound state drastically affects the temperature dependence of the zero-bias conductance (ZBC). In p-wave superconductor junctions, numerical results show various temperature dependences of the ZBC depending on the direction of the magnetic moment in ferromagnets and the pairing symmetry in superconductors such as ${p}_{x}\ensuremath{-},$ ${p}_{y}\ensuremath{-},$ and ${p}_{x}{+ip}_{y}$-wave symmetries. The last one is a candidate for the pairing symmetry of ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}.$ From these characteristic features in the conductance, we may obtain information about the degree of spin polarization in ferromagnets and the direction of the d vector in spin-triplet superconductors.
