The parametric excitation of a mixed pair of quasiparticles in an easy plane antiferromagnet (MnCO 3)

Two tresholds for nonlinear microwave (X-band) absorption were observed at parallel pumping in MnCO 3 at T = 1.7 K. They are interpreted as being the result of parametric excitation of electronic-nuclear spin wave pairs and quasimagnon-quasiphonon pairs respectively.
