In field-driven pinwheel artificial spin ice, island end-states produce a field-induced Heisenberg-like pseudo-exchange coupling that sets the reversal path and explains emergent anisotropies, with strength tunable by island size.

Heisenberg pseudo-exchange and emergent anisotropies in field-driven pinwheel artificial spin ice
In field-driven pinwheel artificial spin ice, island end-states produce a field-induced Heisenberg-like pseudo-exchange coupling that sets the reversal path and explains emergent anisotropies, with strength tunable by island size.
