Abstract

An uncompensated antiferromagnetic surface of CoO is essential for the establishment of exchange bias. Exchange coupling for compensated surfaces is manifested by a large coercivity but no exchange bias field. Degradation of a compensated surface leads to an exchange bias field. These results clarify a key outstanding issue in exchange bias.
