AbstractAn analytical solution with shock-like structure for nonlinear kinetic Alfven waves in a low-beta (beta << m(e)/m(i) << 1) plasma is presented. It is showed that the oblique propagating nonlinear kinetic Alfven wave can rarefy the plasma and lead to a local density jump over a characteristic width of 10 lambda(e) at the wave front, in particular, these new shock-like structure of nonlinear kinetic Alfven waves possess a net field-aligned electric potential drop with a typical order of(2m(e)/m(i) beta)T-e /e >>T-e/e, as a consequence, they can effectively accelerate field-aligned electrons to velocities of order of the Alfven velocity.
