Balanced magnetic logic gates in a kagome spin ice

Abstract
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 functionality has been verified experimentally. However, such gates suffer from a problem in that they sometimes produce erroneous output when integrated into circuits. A fundamental solution is offered by using balanced logic gates: gates for which the ground states corresponding to all possible input states have the same energy. We investigate how balanced gates can be created from kagome spin ice elements. We present a balanced NAND (and NOR) gate consisting of 19 dipole-coupled uniaxially anisotropic magnets. This gate can be either driven by an external clocking field or thermally driven. In the latter case, we numerically show that the gate has a reliability of at least 96%, a number which is shown to be robust against disorder. The presented gate provides a proof of concept for an artificial kagome spin ice NML gate.
