Here we demonstrate that spatially engineered anisotropy gradients provide a deterministic alternative. Using focused Ga+-ion irradiation, we pattern magnetic energy landscapes containing nanoscale \"anisotropy wells\" that confine magnetic domain walls and enable bidirectional sequential switching without reliance on difficult-to-control material disorder.
