The thermal stability of an array of square exchange bias nanoelements has been investigated as a function of both the element size and the microstructure of the antiferromagnetic layer. The thermal stability of the nanostructures is measured in terms of their median blocking temperature < T-B >. It is shown that, generally, < T-B > is lower for nanostructures than for the equivalent thin film system. However, the opposite behavior can be observed depending on the measurement conditions, specifically the temperature of measurement and the setting temperature. These results emphasize the importance/limitations of the setting process in exchange bias systems. (C) 2010 American Institute of Physics. [doi:10.1063/1.3340451]
