Effect of magnetic field processing on the microstructure of micronsize Zn doped MgB2
The pulsed magnetic field was employed in the study on Zn doped MgB2 bulks. A phenomenon that the slurry of Mg, Zn, B and their compounds were excited by the Lorentz force was observed in the pulsed magnetic field process. The critical current density (J(c) ) of Zn doped MgB2 bulks shows great anisotropic dependence on the included angle between the process field and the measurement field. (C) 2007 Elsevier B.V.
