Herein, new spin correlated‐plasmons in Pr_0.6Sr_0.4Co_1−xMn_xO₃ (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 Co⁴⁺, O²⁻, and Mn⁴⁺ is identified. As a function of x, Co⁴⁺ 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 Co⁴⁺, tend to dominate in the metallic phase of the cobaltites, whereas Mn⁴⁺ and O²⁻ are the primary source for the spin correlated‐plasmons in the UV–vis ranges in the insulating phase.

在Pr0.6Sr0.4Co1-xMnxO3中可调谐自旋相关的等离子从红外到紫外线

在此， 展示了在室温下可调且稳定的Pr _0.6 Sr _0.4 Co _{1− x} Mn _x O ₃（x = 0–0.4）中新的自旋相关等离子体。使用先进的光谱技术，可以识别触发自旋极化Co ⁴⁺，O ^2-和Mn ^4+中自旋相关等离子体的电荷，自旋和轨道相互作用。作为x的函数，Co ⁴⁺系统地改变自旋相关等离子体的自旋状态（从高，中，低自旋），这也顺序地将金属钴转变为莫特绝缘体。受钴⁴⁺激发的红外范围内的自旋相关等离激元倾向于在钴的金属相中占主导地位，而锰⁴⁺和O ²⁻是紫外可见光谱中自旋相关等离激元的主要来源。绝缘相的范围。
