We study sequential tunneling of magnetic excitations in nonitinerant systems (either magnons or spinons) through triangular molecular magnets. It is known that the quantum state of such molecular magnets can be controlled by application of an electric- or a magnetic field. Here, we use this fact to control the flow of a spin current through the molecular magnet by electric- or magnetic means. This allows us to design a system that behaves as a magnon-transistor. We show how to combine three…

Spintronics: an insulator-based transistor.
A theoretical study proposes the use of molecular magnets in a type of transistor in which the flow of collective spin excitations transports and processes information.
Spin currents and magnon dynamics in insulating magnets
Nambu–Goldstone theorem provides gapless modes to both relativistic and nonrelativistic systems. The Nambu–Goldstone bosons in insulating magnets are called magnons or spin-waves and play a key role

Nonballistic spin-field-effect transistor.
TLDR
A spin-field-effect transistor based on spin-orbit coupling of both the Rashba and the Dresselhaus types is proposed, which is tolerant against spin-independent scattering processes and the requirement of strictly ballistic transport can be relaxed.
Spin-Transistor Action via Tunable Landau-Zener Transitions
TLDR
An alternative approach in which spin information is protected by propagating this information adiabatically is presented, and it is found that the concept is tolerant against disorder.
Control of Spin Precession in a Spin-Injected Field Effect Transistor
TLDR
The injection and detection of spin between two ferromagnetic contacts are demonstrated and how the magnitude of the spin-current between the source and drain contacts can be controlled by a voltage applied to a gate is shown.
Spin electric effects in molecular antiferromagnets

Will spin-relaxation times in molecular magnets permit quantum information processing?
TLDR
In deuterated samples T2 reaches 3 micros at low temperatures, which is several orders of magnitude longer than the duration of spin manipulations, satisfying a prerequisite for the deployment of molecular nanomagnets in quantum information applications.
Molecular spintronics using single-molecule magnets.
TLDR
This work reviews the first progress in the resulting field, molecular spintronics, which will enable the manipulation of spin and charges in electronic devices containing one or more molecules, and discusses the advantages over more conventional materials, and the potential applications in information storage and processing.

This work proposes to use the polyoxometalate [PMo12O40(VO)2]q-, where two localized spins with S = 1/2 can be coupled through the electrons of the central core, and two-qubit gates and qubit readout can be implemented.

We study spin transport in nonitinerant one-dimensional quantum spin chains. Motivated by possible applications in spintronics, we consider rectification effects in both ferromagnetic and

TLDR
The energy spectrum and the suppression of the leakage-inducing S mixing render the Cr7Ni molecule a suitable candidate for the qubit implementation, as further substantiated by the quantum-gate simulations.
