A physicist who coauthored the discovery of exchange bias with C. P. Bean. Their cobalt particles had an oxide shell, placing ferromagnetism in direct contact with antiferromagnetism. The resulting directional effect in magnetic reversal made the interface an active part of the experiment and motivated the study of coupling between unlike magnetic materials.[ref]
