Nonlinear magnetic resonance is studied in an in-plane magnetized yttrium iron garnet (YIG) film. For YIG films perpendicular to the plane, effect referred as foldover well known. It arises because precession frequency increases with deviation of magnetization. When field reduced, remains resonant demagnetizing decreases The signal disappears when radio pump power insufficient maintain a nonequ...

Yttrium iron garnet Y3Fe2(FeO4)3 (YIG) has a uniquely low magnetic damping for spin waves, which makes it perfect material magnonic devices. Spin waves typically exist in the microwave frequency range and their wavelength can be decreased to nanoscale. Their dispersion YIG waveguides depends on strength orientation of bias field. It may possible explo...

Recently, magnons, which are quasiparticles describing the collective motion of spins, were found to undergo Bose-Einstein condensation (BEC) at room temperature in films of Yttrium Iron Garnet (YIG). Unlike other quasiparticle BEC systems, this system has a spectrum with two degenerate minima, which makes it possible for the system to have two condensates in momentum space. Recent Brillouin Li...
