Abstract:
Herein, new spin correlated‐plasmons in Pr 0.6 Sr 0.4 Co 1− x Mn x O 3 ( x = 0–0.4) that are tunable and stable at room temperature are demonstrated. Using advanced spectroscopic techniques, the charge, spin, and orbital interaction that triggers the spin correlated‐plasmons in spin‐polarized Co 4+ , O 2− , and Mn 4+ is identified. As a function of x , Co 4+ systematically changes the spin state of the spin correlated‐plasmons (from high, intermediate, to low spin), which also sequentially transforms the metallic cobaltite into a Mott insulator. Spin correlated‐plasmons in the IR range, being excited from Co 4+ , tend to dominate in the metallic phase of the cobaltites, whereas Mn 4+ and O 2− are the primary source for the spin correlated‐plasmons in the UV–vis ranges in the insulating phase.
