Abstract
In this study, we investigate the relation between magnetic moment and strain relaxation SrRuO3 (SRO) thin film on SrTiO3 substrate. Epitaxially strained SRO thin films are grown on SrTiO3 substrates with (111) orientation, enabling the examination of the magnetic properties via X-ray magnetic circular dichroism spectroscopy (XMCD) at Ru M2,3-edges. The analysis of the XMCD results using sum rules reveals an increase in the magnetic orbital moment as the thickness of the SRO film increases. These findings shed light on the magnetic behavior of SRO thin films under strain relaxation by increasing thickness and contribute to understanding of the interplay between strain and magnetic properties in oxide thin films.
