抄録
内容記述 Low-frequency electromagnetic thermal fluctuations propagating perpendicular to a magnetic field are theoretically studied with attention to the effect of multiple ion species. In the frequency regime lower than the lower hybrid frequency, there exist three types of modes; magnetosonic mode with ω⋍kγ_A, ion cyclotron modes with ω⋍nΩ_i, and heavy-ion cutoff modes with frequencies slightly higher than the ion-ion hybrid resonance frequencies. The power spectra of magnetic fluctuations due to these modes are obtained analytically and numerically. In a single-ion-species plasma, the magnetosonic mode is an overwhelmingly dominant mode. The autocorrelation function C_k(τ) is thus given by a cosine function with a constant amplitude. In a multi-ion-species plasma, however, the amplitudes of the heavy-ion cutoff modes can be comparable to that of the magnetosonic mode. Therefore, C_k(τ)is initially damped, and its recurrence time is extremely long.
