Abstract

We performed temperature dependent X-ray magnetic circular dichroism (XMCD) measurements at transition metal L2,3-edges. Our results indicate that the interface is a key factor in influencing the superlattices of magnetic moments and observed that the magnetic behavior is different for Fe₃O₄ and Mn₃O₄. The Curie temperature (Tc) of Mn₃O₄ thin film is enhanced at 15K and similar behavior was observed in these Mn₃O₄ superlattices. The temperature dependent magnetic behavior is found to depend on the superlattices bilayer thickness and the number of interface.
