Consequently, the amplitude of a magnetic fluctuation with f ≈ 2 - 5 kHz is suddenly enhanced at the transition timing of Er, and then disappeared after the transition of Er. Furthermore, it is found that the amplitude of Hα signals is enhanced, corresponding to the abrupt diminishing of the magnetic fluctuation with f ≈ 2 - 5 kHz.}, title = {Study of Nonlinear Behavior of Low-Frequency MHD Mode Caused by Transition of Radial Electric Field in LHD}, volume = {10}, year = {2015} }
