Oscillations of past-threshold susceptibility in parametric excitation of electron magnons in antiferromagnetic CsMnF3
Kotyuzhanskii B.Ya., Prozorova L.A.
Parametric excitation of the electron magnons in antiferromagnetic CsMnF3 was investigated at a pump frequency 18 GHz in the temperature range 1.2-2.2 К in the case of strong supercriticality. Oscillations of the past-threshold susceptibility χ were observed. The dependences of the oscillation period τ on Я and P/Pc were measured.
