摘要：

We study the primordial magnetic field generated by stochastic currents produced by scaler charged particles created at the beginning of the radiation dominated epoch. We find that, for the mass range 10(-6) GeV less than or similar to m less than or similar to 10(2) GeV, a field of sufficient intensity to seed different mechanisms of galactic magnetic field generation,while still consistent with observational and theoretical constraints, is created coherently over a galactic scale.
