Spontaneous magnetic fields due to the temperature gradient ∇T_0 produced by a focussed laser beam on one point of a pellet are taken into account in deriving the dispersion relation of Rayleigh-Taylor instability. Growth rate γ decreases with time. Density fluctuation with wavelength shorter than 1.5 (R/L_T)×(n_s/n_0)^1/2 μm is remarkably stabilized, where R, L_T, n_s and n_0 are the radius of a pellet, L^<-1>_T=|∇T_0/T_0|, number densities of solid and the pellet. Validity condition of the theory is γt_0 >> 1 or in another form R >> L, where t_0 is the time of thermal expansion of a pellet and L^<-1>=|∇n_0/n_0|.
