Selective-area grown MnAs nanoclusters are promising components for applications in highly miniaturized future information storage devices. Due to the tuneability of parameters such as size, shape and arrangement of the clusters, their magneto-electronic behaviour can be widely tuned. As a starting point for the investigation of microscopic ordered cluster arrangements, we have studied the transport behaviour of single clusters of different shapes and sizes. For the contacting of the clusters, we used Au contacts structured by electron-beam lithography. The clusters were grown by selective-area MOVPE on GaAs (111)B substrates.
