A longitudinal thermal-diffusion autosoliton generated in the non-equilibrium electron-hole plasma in p-InSb is shown to be diamagnetic in an external longitudinal magnetic field. The phenomenological estimate of the question allows deriving an expression for the magnetization, magnetic induction, and diamagnetic susceptibility of the autosoliton under an external magnetic field. Plots for these expressions, and computations and numerical estimations of the diamagnetism are performed.
