Choose the correct option with respect to magnetic surface anisotropy (MSA).

Choose the correct option with respect to magnetic surface anisotropy (MSA). Correct Answer MSA of free surfaces depends on roughness

The first experimental confirmation of MSA was carried out in 1969. MSA necessarily depends on the chemical state of the surface. It tends to be maximum for free surfaces. This is however reduced heavily upon reaction with gas or any solid coating. The anisotropy of free surfaces varies with the roughness.
