Abstract—

A parametric mode of radiofrequency superradiance was found to emerge upon external exposure of a paramagnetic polymer composite to pulses of elastic waves under high pressure. The composite was a polystyrene matrix containing a system of crossed spins on the basis of Co(QH)₂–O–Co(QH)₂ or Mn(QH)₂–O–Mn(QH)₂ binuclear clusters (QH is a ligand based on QH₂, 3,6-di-tert-butylpyrocatechol), which possess the Dzyaloshinskii–Moriya effect. It was shown that one of the metal atoms of the binuclear cluster in the polystyrene matrix is trapped by the benzene rings of polystyrene by the type of ferrocene. Binuclear clusters form 2D nano-objects with a diameter of 50–100 nm and a thickness of ~1–2 nm. A method for the analysis of these processes and a probable scheme of their emergence are proposed.

顺磁性聚合物复合材料在弹性波脉冲作用下的射频超辐射

摘要-

发现当超磁性聚合物复合物在高压下暴露于弹性波脉冲时，出现射频超辐射的参数模式。复合材料是一种聚苯乙烯基体，包含基于Co（QH）₂ –O–Co（QH）₂或Mn（QH）₂ –O–Mn（QH）₂双核簇的交叉自旋系统（QH是配体）基于QH ₂，3,6-二-叔-丁基邻苯二酚），具有Dzyaloshinskii–Moriya效应。结果表明，聚苯乙烯基体中双核簇的金属原子之一被二茂铁类型的聚苯乙烯的苯环捕获。双核团簇形成直径为50–100 nm，厚度约为1-2 nm的二维纳米物体。提出了一种用于分析这些过程的方法以及它们出现的可能方案。
