Nanomagnetic logic, in which the outcome of a computation is embedded into the energy hierarchy of magnetostatically coupled nanomagnets, offers an attractive pathway to implement in-memory computation. This computational paradigm avoids separate energy costs associated with transporting and storing the outcome of a computational operation. Thermally-driven nanomagnetic logic gates, which are driven solely by the ambient thermal energy, hold great promise for energy-efficient operation, but…

Computational logic with square rings of nanomagnets.
TLDR
A novel design with dipolar-coupled nanomagnets arranged on a square lattice to support transfer of information and perform logic operations and a functionally complete prototype NAND/NOR logic gate is presented that could be implemented for advanced logic operations.
Spin Hall effect clocking of nanomagnetic logic without a magnetic field.
TLDR
This work demonstrates a nanomagnetic logic scheme at room temperature where the necessity for using a magnetic field clock can be completely removed by using spin-orbit torques, and predicts a three to four order of magnitude reduction in energy dissipation.
Experimental Clocking of Nanomagnets with Strain for Ultralow Power Boolean Logic.
TLDR
It is experimentally demonstrated, for the first time, that strain-induced switching of single-domain magnetostrictive nanomagnets of lateral dimensions ∼200 nm fabricated on a piezoelectric substrate can implement a nanomagnetic Boolean NOT gate and steer bit information unidirectionally in dipole-coupled nanomagnet chains.
Engineering Relaxation Pathways in Building Blocks of Artificial Spin Ice for Computation
TLDR
The potential of arrangements of thermally-active nanomagnets based on artificial spin ice for both deterministic and probabilistic computation is demonstrated and it is demonstrated that it is possible to tune the probability of attaining a particular final low-energy state and therefore the likelihood of a given output, by modifying the intermagnet distance.
Selective and fast plasmon-assisted photo-heating of nanomagnets.
TLDR
This work establishes the robust and reliable control of local temperatures in nanomagnetic arrays by contactless optical means by applying a hybrid approach by combining a plasmonic nanoheater with a magnetic element.
Nanomagnetic Self-Organizing Logic Gates
The end of Moore's law for CMOS technology has prompted the search for low-power computing alternatives, resulting in several promising proposals based on magnetic logic[1-8]. One approach aims at
Balanced Magnetic Logic Gates in a Kagome Spin Ice
Nanomagnetic logic (NML) is a promising candidate to replace or complement traditional charged-based logic devices. Single NML gates such as the three-input majority gate are well studied, and their
Programmable computing with a single magnetoresistive element
TLDR
A simple hardware concept for a programmable logic element that is based on a single magnetic random access memory (MRAM) cell that combines the inherent advantage of a non-volatile output with flexible functionality which can be selected at run-time to operate as an AND, OR, NAND or NOR gate.
Computing in Thermal Equilibrium With Dipole-Coupled Nanomagnets
In the 1970s, work at IBM by Charles Bennett suggested the possibility of a computer operating near thermal equilibrium and dissipating energy near the thermodynamic limits. Here, we demonstrate
Sub-nanosecond signal propagation in anisotropy-engineered nanomagnetic logic chains
TLDR
These experiments, and accompanying macrospin and micromagnetic simulations, reveal the underlying physics of NML architectures repetitively operated on nanosecond timescales and identify relevant engineering parameters to optimize performance and reliability.
