The effect of pulsed mechanical activation of radio-frequency superradiation in the parametric mode is established: when an external rheological explosion under high pressure acts on a paramagnetic composite --- a system of crossed spins based on binuclear complexes Co (QH) _2-O-Co (QH) 2 or Mn (QH) _2-O-Mn (QH) 2 (QH --- ligand based on 3,6-di-tert-butylpyrocatechol) in a polystyrene matrix. A possible method for processing data on pulsed mechanical action and a possible explanation of the effect are proposed.
