The torque acting on the magnetization vector in the course of 90° pulsed magnetization of real garnet ferrite films with in-plane and biaxial anisotropy is calculated by a method in which the operating point trajectory is analyzed. The position of the operating point is described by azimuthal angle φ and torque component T m produced by pulsed magnetizing field H m . The time dependence of resultant torque T φ has a sharply ascending portion, within which the nonlinear magnetization oscillations are excited. Additionally, the shape of the curve T φ(t) within this portion depends on pulse rise time τ f only slightly. These results explain the weak dependence of the magnetization oscillation strength on τ f , which was experimentally found previously. It is shown analytically that when τ f decreases to 2.5–3.0 ns within the initial portion of the curve T φ(t) at φ ≤ 10°, there arises an extra maximum of torque T φ. Simultaneously, an additional voltage peak appears in the initial part of the longitudinal magnetization signal. The appearance of the additional voltage peak is confirmed experimentally.
