| Abstract: | The tunnelling conductance spectra offerromagnet/PrOs4Sb12 junctions are theoreticallyinvestigated by using the Blonder-Tinkham-Klapwijk theory. Threepairs of possible candidate for the pairing symmetry ofsuperconducting energy gap of the recently discoveredheavy-fermion unconventional superconductor PrOs4Sb12 arechosen for calculation. We have studied the spin-polarizationeffect on the conductance spectra, with respect to differentstrength of ferromagnetism of the ferromagnet and differentstrength of the interface barrier. Moreover, we have discussed theinfluence of nodal structures of the superconducting energy gap onthe conductance spectra. Different features of the tunnellingconductance spectra were got, which may serve as usefultheoretical comparisons for future experiments. |
