Stimulated self-generated magnetic field and electron thermal transport properties in ultraintense laser-plasma interactions are studied by using electromagnetic relativistic particle-in-cell simulation program. The generation mechanism of spontaneons magnetic and nonlinear saturation process are discussed. Functional relation between linear growth rate of spontaneons magnetic and anisotropic parameters is provided. The state of transport of energy in the heat exchange with electron is analyzed by the Spitzer-Harm theory, and electron′s vertical pyrogenation phenomenon resulting from anisotropic heating of laser is observed. The results may be important for understanding the spontaneous magnetic field generation and fast electron propagation in fast iginition physics.
