Abstract
Weakly ordered nickel-manganese alloys, field cooled to 4 K, exhibit a reversal in remanent magnetization upon warming. The reversal is dependent on the state of atomic order and the cooling field. A local-environment model and Mn-rich aggregates, which are isolated from other Mn-rich aggregates, explain the essential features of the reversal.Keywords
