  Inverse spin Hall effect (ISHE) in ferromagnetic metals (FM) can also be used
to detect the spin current generated by longitudinal spin Seebeck effect in a
ferromagnetic insulator YIG. However, anomalous Nernst effect(ANE) in FM itself
always mixes in the thermal voltage. In this work, the exchange bias structure
(NiFe/IrMn)is employed to separate these two effects. The exchange bias
structure provides a shift field to NiFe, which can separate the magnetization
of NiFe from that of YIG in M-H loops. As a result, the ISHE related to
magnetization of YIG and the ANE related to the magnetization of NiFe can be
separated as well. By comparison with Pt, a relative spin Hall angle of NiFe
(0.87) is obtained, which results from the partially filled 3d orbits and the
ferromagnetic order. This work puts forward a practical method to use the ISHE
in ferromagnetic metals towards future spintronic applications.
