Abstract

Sets of nanomagnets are often utilized to mimic cellular automata in the design of nanomagnetic logic devices or frustration and emergence of magnetic monopoles in artificial spin ice systems, once that unidirectional arrangement of nanomagnets can behave as artificial spin ice, with frustration arising from second neighbors' dipolar interaction, and present good magnetic monopole mobility due to the low string tension among charges. Here, we present an experimental investigation of magnetic monopole population and mobility as a function of lateral and longitudinal distance among nanomagnets. The observed results could be useful in the nanomagnet logic device design and bring new insights about several possible designs for tuning magnetic monopole unidirectional mobility and transport under a low external magnetic field for further application in magnetricity.
