"ALGORITHMS: Switching perpendicular recordings can strengthen domain walls"

Perpendicular magnetic recordings can now be switched from hard (permanent) to soft (erasable) by way of a discovery recently made at the University College London. Using a designer material with strong anisotropy, the researchers demonstrated how to switch magnetic domains from permanent to erasable by applying a longitudinal magnetic field to modulate the domain-walls' strength.
