What is it about?
We study the magnetic anisotropic properties of as-grown and annealed Pd/Co/Pd trilayer films based on their atomic and electronic structures using synchrotron radiation based X-ray absorption spectroscopic studies.

Why is it important?
The effect of temperature on CoPd alloy formation, particularly the relationships among the atomic and electronic structures, magnetic moments and anisotropy of magnetic ion such as Co are not fully understood. To solve these problems, a simple method for synthesizing CoPd alloy with better understanding of factors that enhancing the PMA is necessary.
Perspectives
It is observed that the high temperature annealing rigorously alters the arrangement of atoms in the layer structure. As the spin-orbit interaction plays a major role in PMA, the quantification of spin, orbital moments and electronic and atomic structural properties are essential for better understanding of anisotropy behavior of a material. We have studied the atomic and electronic structural properties of the as-grown and annealed films using synchrotron radiation based X-ray absorption measurements, which are highly proven techniques to study the local atomic, electronic structure and magnetic properties of a material. The observed PMA behavior of annealed film has been discussed in detail with the help of these sensitive techniques.
