To calculate the torque acting on the magnetization vector during the process of 90° pulsed magnetization in real ferrite-garnet films in which, besides in-plane anisotropy, biaxial anisotropy is present, the method based on the analysis of the operating point trajectory is used. Analysis has shown that the shape of the time dependence of the torque Tφ in the time interval, within which the exciting of the magnetization oscillations occurs, is slightly dependent on the pulse front duration. As a result the magnetization oscillations (with a period of Tos ≅ 2 ns) can be observed at the pulse front duration τf ≥ 14 ns.

The possibility of suppression of gyroscopic magnetization oscillations by increasing an effective in-plane anisotropy field is discussed. It is shown that the presence of biaxial anisotropy in real films with the effective field ranging from 10 to 70 Oe should not cause any difficulties at suppressing the oscillations.
