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.
