Query: Spin Amplification by Controlled Symmetry Breaking for Spin-Based Logic   Spin amplification is one of the most critical challenges for spintronics and
spin-based logic in order to achieve spintronic circuits with fan-out. We
propose a new concept for spin amplification that will allow a small spin
current in a non-magnetic spin channel to control the magnetization of an
attached ferromagnet. The key step is to bring the ferromagnet into an unstable
symmetric state (USS), so that a small spin transfer torque from a small spin
current can provide a magnetic bias to control the spontaneous symmetry
breaking and select the final magnetization direction of the ferromagnet. Two
proposed methods for achieving the USS configuration are voltage-controlled
Curie temperature (VC-TC) and voltage-controlled magnetic anisotropy (VC-MA).
We believe the development of new 2D magnetic materials with greater tunability
of VC-TC and VC-MA will be needed for practical applications. A successful
realization of spin amplification by controlled symmetry breaking will be
important for the implementation of existing spin-logic proposals (e.g. "All
Spin Logic") and could inspire alternative ideas for spintronic circuits and
devices.
