The main advantage of the generator is the ability to minimize the threshold current, or even the ability to provide a non-threshold mode for the case of a pure uniaxial magnet, as well as to increase the output power. A new method of nonlinear tuning of a directional spin-wave coupler in the transition from weakly nonlinear to strongly nonlinear operation mode due to nonlinear shift of the spin wave frequency in coupled waveguides is proposed, which allows creating nonlinear magnonic elements operating in ultrashort spin waves range. It is demonstrated that the concentration dependence of the electronic heat capacity has a maximum near the boundary "separating" ferromagnetic and antiferromagnetic alloys, which have to be taken into account during magnetic cooling systems development.
