We present numerical investigations for high-order harmonic generations by a high-intensity chirped-laser interaction with vacuum electrons in the presence of an axial static magnetic field. Combined role of frequency chirp of the laser and a magnetic field enhances the electron acceleration and leads electron energy gain after passing of the laser pulse that generates high-harmonic radiations until the magnetic field diminishes. The result shows that high-harmonic radiations in the range of soft x-rays up to about 10 nm can be generated with common experimental parameters by the proposed scheme of this paper. © 2009 American Institute of Physics;
