We have addressed problems associated with the measurement of zero-field-cooled (ZFC) magnetization and its interpretation in the light of negative magnetization reported in certain ferrimagnetic materials such as CoCr 2 O 4 . We demonstrate that a small negative trapped field in the sample space as
