Investigation of the beyond-threshold susceptibility in antiferromagnetic MnCO3 and CsMnF3 in parametric excitation of spin waves
Kveder V.V., Prozorova L.A.
It was observed that the real and imaginary parts of the beyond-threshold susceptibility in antiferromagnetic MnC03 and CsMnF3 do not depend on the temperature and coincide in order of magnitude with the static susceptibility. The dependences on the static field and on the microwave power agree with the formulas of m.
