This chapter discusses the spin-transfer effect, which is described as the transfer of the spin angular momentum between the conduction electrons and the magnetization of the ferromagnet that occurs due to the conservation of the spin angular momentum. L. Berger, who introduced the concept in 1984, considered the exchange interaction between the conduction electron and the localized magnetic moment, and predicted that a magnetic domain wall can be moved by flowing the spin current. The spin-transfer effect was brought into the limelight by the progress in microfabrication techniques and the discovery of the giant magnetoresistance effect in magnetic multilayers. Berger, at the same time, separately studied the spin-transfer torque in a system similar to Slonczewski’s magnetic multilayered system and predicted spontaneous magnetization precession.

Spin Torques

The spin–orbit coupling spin torque consists of the field-like [S. G. Tan et al., arXiv:0705.3502 (2007).] and the damping-like terms [H. Kurebayashi et al., Nat. Nanotechnol. 9, 211 (2014).] that have been widely studied for applications in magnetic memory. We focus, in this paper, not on the spin–orbit effect producing the above spin torques, but on its magnifying the damping constant of all field-like spin torques. As first-order precession leads to second-order damping, the Rashba constant is naturally co-opted, producing a magnified field-like damping effect. The Landau–Liftshitz–Gilbert equations are written separately for the local magnetization and the itinerant spin, allowing the progression of magnetization to be self-consistently locked to the spin.
