Abstract

Abstract We study the charge conductance in ferromagnet/spin-triplet superconductor junctions with the helical superconducting states, k x x ˆ ± k y y ˆ or k y x ˆ ± k x y ˆ , which are consistent with the in-plane H c 2 , a b measurements of Sr 2 RuO 4 . The conductance shows strong anisotropic dependence on the orientation of the magnetization in ferromagnet and is simultaneously symmetric about some specific rotations. The effects of the magnetization magnitude and the height of the interfacial barrier are also investigated. The obtained results may provide helpful information about the pairing symmetries in Sr 2 RuO 4 .
