摘要：

We present the fabrication and exploration of arrays of nanodots of SrRuO3 with dot sizes between 500 and 15 nm. Down to the smallest dot size explored, the samples were found to be magnetic with a maximum Curie temperature T-C achieved by dots of 30 nm diameter. This peak in T-C is associated with a dot-size-induced relief of the epitaxial strain, as evidenced by scanning transmission electron microscopy.
