# Magnetic Properties of Epitaxially-grown $SrRuO_3$ Nanodots

## TL;DR

This study investigates the magnetic properties of epitaxially-grown SrRuO3 nanodots, revealing size-dependent Curie temperatures and strain effects, with the highest T_C observed at 30 nm dot size.

## Contribution

It demonstrates how nanodot size influences magnetic behavior and strain relief in SrRuO3, providing insights into nanoscale magnetic property tuning.

## Key findings

- Maximum Curie temperature at 30 nm dot size
- Strain relief correlates with dot size
- Nanodots remain magnetic down to 15 nm

## Abstract

We present the fabrication and exploration of arrays of nanodots of $SrRuO_3$ with dot sizes between 500 nm and 15 nm. Down to the smallest dot size explored, the samples were found to be magnetic with a maximum of the 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.
