✦ Synopsis

The old problem of turbulent diffusion is addressed to define the influence of rotation and magnetic fieldthe usual ingredients of astrophysical bodieson the effective transport coefficients. Either rotation and magnetism produce the anisotropy and quenching. The tensorial structures of the diffusivities and their dependences on the angular velocity and the field strength are explicitly defined. A n example of application of the theory to the global stellar circulation model is given and the implications for cosmic dynamos are briefly discussed.

## Abstract The effect of applied rotating and combined (rotating and static) magnetic fields on silicon transport during the liquid phase diffusion growth of SiGe was experimentally studied. 72‐hour growth periods produced some single crystal sections. Single and polycrystalline sections of the pr
