We here leverage scanning probe microscopy, sensitive to both structural and functional properties of ferroelectric domains, in order to change, measure, and characterise the variety of transitions (and transition-like behaviours in the highly nonlinear dynamics accompanying polarisation reversal or switching) observed, with the end goal of better understanding these nanoscale transitions, for their universality to other systems and applicability to potential future devices. We hope that this work details key technical improvements in the measurement and analysis of power-law dynamics, and key scientific discoveries in describing the behaviour of both their ferroelectric and structural domains.
