摘要	The exchange bias (EB) effect and its thermal stability in nanoscale Co/NiO antidot arrays and sheet films have been investigated. The EB field H-E increases with increasing Co thickness (t(Co)) and reaches a maximum at t(Co) = 8 nm in the antidot arrays, whereas H-E decreases with t(Co) in the sheet films. Compared with the sheet films, H-E in the antidot arrays is either enhanced or decreased, depending on the thickness of the ferromagnetic Co layer, which is due to the three-dimensional effects in the antiferromagnetic NiO and ferromagnetic Co layers caused by the nanopores. A higher thermal stability is observed in the antidot arrays due to the out-of-plane anisotropy constant K-1 of the misaligned antiferromagnetic magnetization component.
