Dependence of the efficiency of spin Hall torque on the transparency of Pt/ferromagnetic layer interfaces

Year: 2015

Type: article

Abstract: A systematic study of both the harmonic response and spin torque ferromagnetic resonance demonstrates that the spin Hall torque efficiency in a Pt-ferromagnetic (FM) structure is strongly dependent on the interface properties and the choice of the ferromagnetic materials, a key point that has until now not been made in spin Hall studies.
