Radiofrequency Superradiance on Exposure of Paramagnetic Polymer Composites to Elastic Wave Pulses

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.
