Abstract. The forced nonlinear
magnetization second order precession in normal magnetized plate having
magnetoelastic properties is investigated. The orientation transition of
magnetization vector which consists in variation of vector equilibrium position
by magnetoelastic constant variation is analyzed. The equation system for
equilibrium position of magnetization vector relative to magnetization and
elastic displacement components which was resolved by Kardano method is found. The
parametrical portraits for magnetization and elastic displacement are constructed.
The role of magnetoelastic interaction in these portraits’ form is investigated
on the basis of potential model. Two models was proposed for interpretation of precession
period dependence from magnetoelastic constant value: effective fields and
quadratic magnetoelastic connection.
Key words: magnetization precession,
magnetoelastic interaction, parametrical portrait.
