A single continuous white line drawn left to right on black: it begins as a dense tangled knot, loosens into wide open loops, then straightens and folds back on itself into a stack of neat parallel lines, like lines of text on a page.

An invited overview of what is and is not yet understood about this magnetic 'memory' effect in stacks of atomically thin magnetic materials, and where the field needs to go next.

Invited, peer-reviewed perspective, invited on the strength of the three Fe3GeTe2-based exchange-bias research articles above. No analysis repository is associated with this perspective article.
