Investigation on the optical properties of annealed Mn-Co-Ni-O thin films by spectroscopic ellipsometry

Mn-Co-Ni-O thin films have been widely used for their excellent negative temperature coefficient features, but investigations about tailoring their structural and optical properties via a post-annealing (PA) process are still rare in recent years. In this Letter, we derived the visible to ...
