Abstract
A study is made of the influence of nonlinearity upon the structure
of a
steady-state disturbance brought about by low-frequency
(ω[Lt ]ωi) monochromatic
magnetosound propagating in a transversally inhomogeneous low-pressure
plasma
(β[Lt ]me/mi),
in the vicinity of the Alfvén resonance
point for the case when the principal
linear mechanism for forming the transverse structure is provided by magnetic
field
diffusion due to small plasma resistivity. It is shown that the nonlinear
properties
of the fundamental harmonic of a disturbance are determined by its self-action
through a plasma density variation that it produces. The disturbance structure
in
the region of the Alfvén resonance is described.
