Selective-area MOVPE-grown ferromagnetic MnAs nanoclusters are very interesting building blocks for completely new miniaturized magnetoelectronic devices in planar geometry. Due to the cluster growth on pre-patterned substrates, it is possible to tune their size, shape and position with high accuracy. This yields a high degree of freedom in the growth of various MnAs nanocluster devices for new planar magnetoelectronic applications. We report on the preparation of contacted, single MnAs nanoclusters and nanocluster arrangements consisting of clusters of different size and shape as well as the investigation of their structural and magnetotransport properties.
