Abstract

The effect of quantization of strong magnetic fields in laser-produced plasmas has been investigated experimentally by means of Faraday´s rotation and theoretically by computer RMHD modeling for the first time. It is not surprisingly, because of the Maxwell equations in matter have the same closed symmetry as Dirac equation in quantum mechanics. The observed “plasma droplets” have anomalous high lifetime and fine structure. Their typical diameters range from 10 to 200 μm. In the vicinity of such droplets a 1-5 miniature magnetic dipoles has been detected. The measured magnetic fields by means of Faraday rotation method are as great as 4 - 120 MG at distance of r ≈10 -14 μm.
