Abstract
We present the fabrication and exploration of arrays of nanodots of SrRuO<sub>3</sub> 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<sub>C</sub> achieved by dots of 30 nm diameter. This peak in T<sub>C</sub> is associated with a dot-size-induced relief of the epitaxial strain, as evidenced by scanning transmission electron microscopy.
