This letter reports the first detailed measurement of $M_z$, the component parallel to the effective field direction, when ferromagnets are excited by microwave fields at high power levels. It is found that $M_z$ drops dramatically at the saturation of the main resonance. Simultaneous measurements of $M_z$ and absorption power show that this drop corresponds to a diminution of the spin-lattice relaxation rate. These changes are interpreted as reflecting the properties of longitudinal spinwaves excited above Suhl's instability. Similar behavior should be expected in spinwave emission by currents.
